Term for an English male, usually a pipe smoker, who has immigrated to the U.S. and lost his accent except when pronouncing "aluminum". Commonly found in bars, bitching about how much better English lager is compared to "American piss water".
!Warning! The bar hopping grolleg may, with some effort and a few rounds, be able to switch on his native accent in order to get some sweet all American ass. Should you encounter this chick steeling Brit, suggest a smoke break. Upon this suggestion he will offer the lush ladies a "fag" and promptly be accused of gay bashing. Please enjoy the ensuing violence as the Grolleg is obligated to exit said bar.
"Dude, that Grolleg won't shut up about how he got gypped on his pint"
"I know, and if he says "smashing" or "winning" to my girlfriend one more time, I will fucking show him "bloody hell.""
