v. When one chugs their alcoholic beverage in celebration, due to the fact that school is cancelled the following day because it's a MOTHER FUCKING SNOW DAY!

n. A smoke-show who would not be at the bar on a normal weekday, but due to the fact that there's a snow day will be in attendance.
I just got the Cougar Alert that there's a snow day tomorrow, time to snow day slam this beer.

Upon receiving the Cougar Alert that class was canceled tomorrow, i immediately ran to the fridge and snow day slammed a coldie.

"Dude, I saw you take home that snow day slam last night; well done."
