Get the BAMFs mug.
An onomatopoeic sound of teleportation, especially when done by Nightcrawler of the X-Men.

It also can be used to refer to the act of teleporting.

The act of being a BAMF, or a Bad Ass Mother Fucker. Usually refers to a group of bestfriends who go out almost every night and do crazy shit.
Steph, Caitlyn, Devin, and Kaitlynn were totally BAMFing it up last night at that party.

Originated from Marvel comics, it was originally Night Crawlers sound affect when he would teleport. However, Dane Cook likes to be a stupid douchebag and take all the credit and uses the term BAMF as 'Bad Ass Mother Fucker'
Dane Cook: And I was like MAN I'M SUCH A BAMF!

Night Crawler: SHUT UP YOU STUPID BITCH! YOU TAKE ALL MY SHIT!
