In the world of collectable card games (especially magic the gathering and hearthstone), to punt is to make a mistake that causes you to lose a game you were otherwise winning.
Sometimes, people loosen the definition to include all mistakes made in a game, regardless of whether they would actually change the outcome.
I should have realized I had lethal, but I punted by targeting my lightning bolt at my opponent's creature.
"Your a punt!"
"DID YOU JUST CALL ME A CUNT?"
"No i said punt."
"Is that like a pretty cunt?"
noun
A word for a person of a larger size with a big tough-guy attitude. Usually a ginger, and always accompanied by their "peewee", a small, skinny counterpart that looks to duh "punt" to pelt others.

Taken from the sport of football, punting is a passive-aggressive way of delaying an action or an inevitable result. When someone punts, it's usually because they are faced with an uncomfortable situation where they are afraid to give a clear answer, response, or explanation to avoid judgment, ridicule, or scorn.
"I asked Tony if he wanted to hang out, shoot some pool and get a couple of brews. Instead of telling me directly that he really didn't want to go, he punted, saying he needed to ask his wife first. Tony wanted to avoid the uncomfortable situation of possibly hurting my feelings, so he made his wife the scapegoat, because everyone knows what a selfish, possessive bitch she is."
