Itchasketch 

Pictures and patterns created in the seat of ones underwear from continual, and sometimes painful rectal itching.

Darling, you have an image similar to the 'Study after Velazquez's Portrait of Pope Innocent X' in the gusset of your y fronts.
How did that happen?

Ahhh that, it was a simple, yet furious itchasketch I created during a meeting this afternoon sweetie!

Etchasketch Night

Typically a night in which there was alot of drinking or smoking which resulted in you doing something you regret with someone. Like with an etchasketch toy you would draw something and shake it and make it erase

"Dude I got drunk last night and fucked that fat chick"

" Errrrr dude thats an etchasketch night"

etchasketch 

Very Sketchy. Alternative to hella sketch, which is a californian slang. Etchasketch is more viable to the general teenage audience. Use it with caution.
