Katherine Heigl That Shit

A command told to a female with unattractive un-bra'd breasts.
The definition originates from the movie Knocked Up, where our actress is seen having intercourse with a bra on.

My ex-girlfriend's tits were so nasty without a bra on I told her to Katherine Heigl that shit.
