Pumper Slug

A real firefighter. The only kind that ride Pumpers (engines) and put out the fires. Not a truckie.

Have you ever seen a truckie actually put out a fire? No, because that's the pumper slugs job. The truckies just stand around flexing for the camera.

Party Pumper

A person who brings hype and enthusiasm to a party, who helps break the ice so partygoers have a good time.

My university's student newspaper always had wanted ads for 'party pumpers' to work at bar/bat mitzvahs getting the kids dancing and enjoying themselves.
