One's 21st Birthday, when it's customary to drink 21-shots plus one for "good luck"
Jim: Hey, how was your birthday?

Kyle: I had 6 shots of JB, 3 of Jager, 5 of vodka, and chased the 8 shots of tequilla and I didn't boot.

Jim: Dude, you've got crazy tolerance, I'm glad you had a happy Barfday.

Adam: Hey how was your 21st barfday?

John: I puked twice at the bar and woke-up face-down in the toilet. I don't remember anything else. It rocked!
