Bum Rush

...Oh, thank you Simpsons, I now completely don't understand the Americanism "Bum Rush"...meaning, as I thought, based on Will Smith's "Wild Wild West" (wiki-wiki-wild!...ahem...) - to mean (and I quote myself) "to have the shit kicked out of one in an uneven contest of strength" the SkyOne episode aired this evening seems to hint that to "Bum Rush" is to throw a tramp/drunk person with force out of a drinking establishment...it does make me wonder what US dictionaries look like... ;)
