Someone who is being ridiculous and overly pathetic, in the same instance. Often times a spoiled child who thinks they are entitled to everything, yet in reality, they deserve nothing.
Man, Ericka's sister is being a TOTAL Twat Burger right now.
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"
