When multiple flushes will not remove everything on the inside of a toilet after taking a dump. This can be particularily embarrassing at a house party where there's a single bathroom that everyone is using.
Dude, I couldn't help myself...I had to go. Unfortunately I bruised the porcelin and had to use some toilet paper to finish the job the toilet couldn't.
Gymprovisation is when you have to use equipment other than the standard equipment available from the gym's selection.
Gymprovisation comes in two forms:
A) a hotel or other gym with a limited selection might require you to gymprovise in one way or another.
B) you might be such a workout freak that you need to gymprovise to hit that muscle "just right".
You should be careful with option B because it can come across as douchy.
Bill: Man that muscle head is ripped.
Jane: Yeah, he must use gymprovisation to get a body like that.
