british slang, originating from pilsley, derbyshire: a weak expletive which shares both its definition and conventions of use with the word b-st-rd. 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 b-st-rd is used in precisely the same way. as an antidote to your ignorance, other examples of intensifiers are: f-cking, bl–dy, chuffing, sodding, etc.
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!
