describing someone or something totally UNsmooth & hilarious. a very dubs thing to do would be to use the phrase "that's what she said" after EVERYTHING. and to overuse "your mom" jokes. for example, an obese cat yawning is dubs, a nerdy dude tripping & bleeding to death is unsmooth & dubs, a pathetic troll-like girl with a manly voice attempting to "flirt" with nerdy dude tripping & bleeding to death is also an example of dubs.
"toby mcguire was soooo dubs when he acted emo in spiderman 3"
dude 1 - "woah, i can't believe i just tripped and fell in front of that smokin' hott girl. how embarassing."
dude 2 - "bro, that was so dubs."
