scut•tle•head /ˈskədlˌhed/ (see also, scuddlehead)
1. noun (pl. -s)
An ethnic or racist slur directed at or towards an undefined race or ethnicity. Insult to all, compliment to none. A potent fighting word, if you can bring yourself to be offended by it. Most common among racist taxi drivers in Portland, which isn't a home to racists.
Origins found in Yorkshire saying 'coal-scuttle in the mouth', though shortened through Cumbrian slang.
Traditionally used as a reposte to an insult, equivalent to the unpleasant experience of physically trying to put a coal scuttle in your mouth.
Alternatively can be abbreviated to a simple 'Scuttle'.
