"See you tomorrow"
"Ok D.A.B."

"I hate her. She's such a dab"

D.U.G.G. 

Stands for "Designated Ugly Gay Guy." The male counterpart to any one attractive female. This male is OVERLY gay, participates in the Flag-Core for his high school band, can be seen on the dance team, and you normally have to befriend him in order to get some ass from the attractive female. (Tips to befriend the DUGG: buy him hair gel.) Good luck!
