Fansler 

When someone performs such a hard core drum solo that the shirts on people in the audience rip off from their bodies and the words "Bitch yeah" are branded into their skin from the instense heat of rock.

"Yeah, the drummer totally pulled a Fansler!"

Fissler

Verb. A minor sexual assault similar to groping or molesting, the act is usually carried out on a female by a male who has been a “friend” of hers some time. The act is usually a precursor to a more serious assault.

Girl 1: “I was out with Todd last night and he fisslered me, I feel abused.”
Girl 2: “That’s terrible! Maybe you should go to the police.”
