Seeing as Teapots are the puzzle of the day, i thought i'd give it a go,
I have one word which has several (2 or more) meanings. Each of the meanings is a teapot (first, second ...) You try to figure out the word with my Hints.
My first teapot is supporting
My second teapot is a bit of a turn on
My third teapot you'll get a kick out of
My fourth teapot contains a spare
hopefully its not too easy, i can always add hints later if required
