Someone with a large, over proportioned forehead, making their tall head look like a loaf of bread. Short hair or a receding hairline can make this look worse. Shortened to LOBH.
For example Ant Mcpartlin has a Loaf of Bread Head. "look at Laurence's head, its so big" "your'e right, it kinda looks like a Loaf of Bread" "yeh, he's got a LOBH"
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"
