When you sneeze and puke (whether it be in your throat or spit out) all over the place
Tends to happen when you laugh too hard.
Also can be called speezing
Person 1: Dude I just totally spuked!
Person 2: What the heck is that?
Person 1: Bleh, I just speezed
Person 2: Speezed? Isn't that when you sneeze and puke and stuff?
Ulzzang true definition is "best & "face" = best face in korean. They are basically people with above average looks, sometimes with the use of photoshop and haduri who post their pics online, some becoming internet celebrities.
"Hey, see that chick over there? She's pretty enough to be an ulzzang. :D"
