"Swoofter" - originally a contraction of "pull a swift booster pal", now used in many other contexts.

To be told to "pull a swoofter" is loosely equivalent to, in the vernacular, "get the fuck out".
"Fuckin' pull a swoofter"
"Double dunt a swoofter and fuck off"
"Get your rat out ya pure swooftcake"

etc.
