Divided by a common language

I think America’s great. To help maintain the special relationship between our two countries, here’s a handy guide to US lingo for Brits:

bullhorn – lies told by sexually aroused male
cellphone – be free from slavery
duplex – deceive a superhero’s arch-enemy
faucet – what to do to a tap when it’s stuck
freeway – manner of dress involving elasticated-waist trousers (q.v. beltway)
hobo – dual-purpose garden tool: can remove weeds and fire arrows
jello – a wobbly, out-of-tune string instrument
ladybug – electronic device for eavesdropping on high-society women
popsicle – exploding scythe substitute; a must-have for every busy modern grim reaper
sidewalk – crab-like motion
spigot – saliva produced by jockeys
teleprompter – family member who reminds you that their favourite programme is about to start on a different channel from the one you’re watching
turnpike – become fishy
wiener – foodstuff that coaxes you away from consuming liquids
zip code – secret method of undoing a dress in the dark

Any additions most welcome. Some suggestions: diaper, pacifier, spigot, realtor, caboose, downtown, station wagon…
