I just thought of some more handy English words and phrases that I've picked up either on this forum or elsewhere...

"shite"
"starkers"
"gobsmacked"
"knackered"
"a good rogering"
"knock me up" (usually "in the morning")
"bonnet" (automotive term)
"boot" (also an automotive term)
"thump" and "a good thumping"
"piss off"
"taking the piss"
"randy"

They're surprisingly earthy, aren't they? They all make me think of Olive Whatnoll and 'er 'usband, Eddie, 'oo live in 'Ull.
