# What is a Breech Phrase™?

This is in the spirit of the What is a Word/Phrase™ series inaugurated by JLee with his original Phrase™ and Word™ puzzles.

If a phrase adheres to a certain rule, then I call it a Breech Phrase™.

Use the examples below to find the rule.

In case you want it in CSV:

BREECH PHRASES, NOT BREECH PHRASES
UNFIT CROWD, INEPT HORDE
SLUG DRIP, WORM OOZE
COCKY OASES, BRASH FONTS
HIDE POTS, BURY PANS
ONCE CALM, THEN COOL
WET DOG, DRY CAT
DUMB PAIR, MUTE TEAM
BOXED TUNER, CASED GIZMO
DATE TIPS, GIRL HINT
NEW AIR, OLD GAS
BIRD MARK, CROW SCAR
HER IVY, HIS GEM
DRY BUG, WET FLY
ONYX NODE, INKY SITE
LAST BAIT, ONLY LURE


Bonus Puzzle:

If a Breech Phrase™ possesses a certain property, then I call it a Twin Breech Phrase™. What is a Twin Breech Phrase™ and how many examples of it can you give?

• Is the cipher tag really applicable? – CodeNewbie Nov 3 '16 at 5:27
• Isn't it? The property the phrases possess involves a cipher... – GoldenGremlin Nov 3 '16 at 12:00
• Not to toot my own horn, but Riven Words™ are based on a very similar concept :) – user812786 Nov 3 '16 at 17:53
• @whrrgarbl Those are phrases, though. – EKons Nov 3 '16 at 18:05
• @ΈρικΚωνσταντόπουλος Of course, I didn't mean to suggest they were exact duplicates. I just noticed that they are based on similar operations. – user812786 Nov 3 '16 at 18:35

A Breech Phrase™ is one where

The second word is the reverse of the rot-$n$ encrypted first word for some number $n$.

Examples

If we apply the rot-9 cipher to UNFIT, we get DWORC which is CROWD backwards.
If we apply the rot-23 cipher to SLUG, we get PIRD, which is DRIP backwards.
If we apply the rot-16 cipher to COCKY, we get SESAO which is OASES backwards.
If we apply the rot-16 cipher to BOXED, we get RENUT which is TUNER backwards.
If we apply the rot-14 cipher to WOMB, we get KCAP which is PACK backwards.
If we apply the rot-8 cipher to LAST, we get TIAB which is BAIT backwards.

Bonus Question

My guess would be that a Twin Breech Phrase™ could use the same word twice. Obviously, every palindrome which is sufficiently grammatically flexible provides us with a trivial Twin Breech Phrase™ but we can also find some more:

rot-13
CHERUP CHERUP
FANS FANS (which means cools down the supporters via a wafting motion)
ROBE ROBE (which means to wrap a robe in a robe)
REBORE REBORE (which means to make a new wider boring out of one that already exists)

Meaning of Breech

One possibility, as pointed out by Dan Russell in the comments, is that this refers to a 'breech' birth - when a baby is born feet first, so reversed (and possibly rotated).

• Great answer! Do you have any ideas about why they are called "Breech Phrases"? – GoldenGremlin Nov 3 '16 at 11:59
• A "breech" birth is one where the baby's feet come out first, so reversed (and possibly rotated as well). – Dan Russell Nov 3 '16 at 13:49
• Thanks @DanRussell. I was also thinking that a breech phrase has a pair of words, like a pair of breeches and that the words are somehow 'opposite' like left and right? – hexomino Nov 3 '16 at 13:55
• @hexomino That sounds reasonable too, though now my brain is going to a baby being born feet first into a pair of pants, or twins being born feet first, one into each leg of a pair of pants... – Dan Russell Nov 3 '16 at 14:05
• @DanRussell, you're on the right track with breech (or backwards) babies. How are these babies commonly delivered? That's the last dot to connect in explaining the name of the phrase. – GoldenGremlin Nov 3 '16 at 23:49
