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.
2. adjective (-ed)
Having the qualities of a scuttlehead.
You know what the problem is, don't you? Too many damn scuttleheads!
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'.
"She told me I was ugly and that was a right scuttle in the mouth"
