word - Teapot Riddle no.33

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

Answer

I think your teapots are

boots.

My First Teapot is supporting

If you are wearing boots then they support your feet.

My second Teapot is a bit of a turn on

"Booting" is what your computer does when you turn it on.

My Third Teapot you'll get a kick out of

Like the last one, this is verb rather than noun: to boot something is to kick it.

My Fourth Teapot is Contains a spare

The boot of your car.

Discarded teapots:

The second could have been more literal -- some boots are designed to be sexy and some people are very much into that sort of thing. The third could have been a reference to football boots or to "kick boots". (I got #2 right on my own but needed some prodding from OP to get #3.)
