Senior Sunday
That day when all the senior girls in your high school post cute pictures of themselves, causing you to masturbate violently.
Senior Sunday would be really nice if I had a girlfriend.
Senior Sunday
Every Sunday, you take all your collected roaches from the week prior and make a generation joint out of them. This generation joint is "older" than the other joints, hence the name.
Dude I'm so pumped for this week's senior Sunday, I have 30 roaches and some foot long papers
Senior Sunday
An excuse for every senior girl in America to post pictures as a way to fish for compliments and likes.
“Oh my God Rebecca don’t forget to post your picture for Senior Sunday!”
