something you say right before or after saying something arrogant to acknowledge it and therefore not seem like an ass. (similar to how one uses "no homo" or "no offense")
can also be used to call other people on their arrogance (see 'you have nice legs')
"my science project went so well! I think mine was the best in the class...and I have nice legs"
"I have nice legs but damn I look hot with this new hairdo"
