underdecking 

conspiring against an authority figure to take synchronized shits underneath said authority figure's deck. Usually performed in groups of two to five people. In extreme cases, shit burritos are fashioned with paper towels and left to be found.

Oh, no. Have you seen the kids? I hope their not underdecking us again!

underdesking 

The office skills utilized by those who prefer to smother their bosses undersides with their noses and kisses.

Although Jill's typing and filing skills lack any true ability, her underdesking talents may be the reason she is till employed.

Underwearing 

Wearing so few clothes you might as well be wearing only underwear.

Girl: that girl's clothes are so skimpy, she is such a slut
Dude: yeah, love it when girls go around underwearing.
Other dude: yes, girls that underwear as so sexy.
