look up any word, like yeet:
 
28.
A condiment that everybody who is young, like under 18 years old hates,except for a few people who can't stand cream based, sauces,though fewer and fewer people who are young and healthy eat this yellow paste because, supposedly it burns there palate, and it stings there nostrils, the way mustard gas burns up people.
It is projected by the Condiment survey, that by the year 2010, fewer than 2.5 percent of the population will eat mustard,

12 year old in 2010: Ewwwww!!! Does this have mustard on it?!?! I hate mustard!! Where is a knife so I can get this off my burger?

Parent in 2010:(thinking to self) Man, when I was a kid, mustard was still large in picnics. What is up with so many people hating it now?

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, bloody, 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!
