Fister saster caster unit 

An imaginary (yet vital) loose part hanging from underneath an unsuspecting motorist's car. Alerting unsuspecting motorists about said item is of supreme importance. Mission accomplished when unsuspecting motorist pulls over and gets out to see whats wrong with his car.

Driver 1: (while pointing at undercarriage) "Hey Sir, your Fister saster caster unit is out"
Driver 2: "What"?
Driver 1: "Your fister saster, the caster unit, it's out" (still pointing)
Driver 2: "oh really?!? oh, um ok" (pulls into rite-aid parking lot)
Driver 1 then laughs laughs laughs all the way to work.

Plump Sister 

A woman who has put on a few pounds since the last time that a random 72 year old Uncle will say to Larry, the cousin twice removed, this kind of thing:

Uncle: "Golly! That's Suzanne? She has gotten to be a real Plump Sister since the last time I saw her."
Larry: "Must've been back in the Seventies. Before the kid. Kids. Who knows."

Uncle: "It was May 1979. When they got married...wow she just blimped out!" Larry: "Total butterball. Plump Sister, shame."
