Get the Oofmug. An oof that is significantly larger than a standard oof. Mega oof crosses the line to where it is actually insulting whereas an ordinary oof only states that the used does not care about the tragic event that they have just found out about.

Winston - oh

Get the Mega Oofmug. An innocent-sounding, Hawaiian-pidgin slang term meaning “to have sex”, “fucking” or “screwing”. It sounds like a sound-effect, and most people will think so. But it can be used by well-travelled individuals in a pick-up line, sounding worldly and classy, while still getting the point across.
