A drinking game to be played with a group of people and alot of beer. You sit in a circle and begin playing the song "Thunderstruck" and designate an order to go in. Everytime they say "thunder" the next person begins drinking, and drinks until the next time they say it, then the guy next to him drinks...Whoever gets hungup on a guitar solo gets truely thunderfucked.
"She took my presentation, put her name on it and took it to senior management again. Total thunderfucker."
"Ill send it to them the night before it's due, make that thundafucker look like the idiot they are when they open their mouth"
Not to be confused with "Fundafucker" - which is the out of office equivalent.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
