look up any word, like fleek:
 
1.
1. one of your bros who goes out drinking with you, gets plastered and then proceeds to crush any chance you have of sustaining a conversation with an attractive stranger for more than, say, 5 minutes.

(e.g. "he's scaring me")

2. that same guy about 15 minutes later falling asleep on the bar, forcing you both to leave.

(e.g. "uh... go take your drunk brother home")
"Wow, gato. You are the worst wingman ever."
