undershirt 

1. what manuel neuer never fails to wear on pitch.

2. it is the teasingly thin cotton shirt usually seen worn by usually hot-the-ones-you-fancy footballers underneath their jerseys.

3. it is the very thing that most fans(girls) hate to see once the footballers pull off the shirts after the match.

4. it can be used as a test to see if a girl is straight or not. nuff said!

undershirtable 

The ability for an often-times too small t-shirt to be used exclusively as an undershirt, mostly worn under polos. This term refers mostly to preppy teenage males but it can apply to many different male groups.

Walker: Man... I was brushing my hair for the third time this morning and I noticed that this T-shirt is way too small for me now.
Trey: Don't worry, its still totally undershirtable. I've got like a whole closet full of them.

Undersit

Sit is the opposite of stand right?
If thats the case, Undersit is the opposite of understand.

Undersit: to misunderstand

If undersit just isnt good enough, then use something that is more of an opposite, like underlaydown or underdie.

I undersit why someone would want to put a rabid monkey in a washing machine
