British slang, originating from Pilsley, Derbyshire: A weak expletive which shares both its definition and conventions of use with the word bastard
. Originally, "mustard" was used to refer to a child born out of wedlock, but through a process of semantic broadening, it is now mostly used as a general pejorative term. It can be used both as a noun (see example one) and an adjectival intensifier (see example two). The word bastard
is used in precisely the same way. As an antidote to your ignorance, other examples of intensifiers are: fucking
Example one: My phone's such a mustard; the autocorrect feature has made a fool of me yet again.
Example two: Arghh, my mustard phone has caused me ridicule!
