#YOSO

A douchebag way of rubbing into people who aren't seniors. Stands for "You're Only a Senior Once". Using it too much will cause people (underclassmen) to hate you.

Junior: Oh shit nigga, I got soo much AP Bio HW, looks like I can't make G's awesome ass/thug party.

Senior: Hahaha sucks. #YOSO son. I don't gotta do shit nigga

#Yolo

The absolute worst internet THING created, second to (i shudder to type): SWAG.

Meaning You Only Live Once, it practically makes you believe you can do ANYTHING and you have the right to do everything, no matter how stupid. The people that say this practically enter derp moments.

Tim: #Yolo I just downed 5 kegs of beer #Yolo
Frank: Yolo. You. Only. Live. Once. Don't f***ing waste it. By the way, you are a real derp.

Note: These are random names.

#yoloswag4jesus420blazeitfaggot

A phrase that was popular on Twitter in 2012, that combined multiple ignorant phrases (YOLO, swag4Jesus, and 420blazeitfaggot) into one perfect shitstorm of ignorance. Essentially, it is an unneccessarily complicated way to say YOLO/fuck it/do it for the vine. Used in a serious manner by fools and airheads, but in an ironic one by people in posession of a normal intelligence.

Dude 1: Dude, you should TOTALLY go of that jump, bruh!

Dude 2: But why?

Dude 1: BECAUSE WHY NOT, DUDE?

Dude 2: Oh TRUE!

Dude 2 (as he goes off the jump): #YOLOSWAG4JESUS420BLAZEITFAGGOT!
