The bigger version of me is used to make marriages faster
At least, that's what they show on TV
I'm known to the U.S, young and old
Although programmers personally prefer me the most
In fact, I hear they have stacks of me!
The title matters!
The answer is:
Push pop is a candy and programmers push and pop elements in stacks. I'm still thinking about marriage and young and old. There's been a jumbo push pop commercial on TV, where the jumbo push pop speeds the wedding up. Push pops were introduced by a U.S. company in the 80s and is still popular today.
