Crap is used as an interjection when something goes wrong.
Colloquially, and somewhat vulgarly, crap means ‘excrement’ or ‘the act of defecation,’ and ‘junk’ or ‘litter’ (a word that describes paper, cans, or general garbage that people throw).
- «Oh crap!» Mary exclaimed, as the plate hit the floor and shattered.
- Joe stepped in some crap on the sidewalk.

Also very colloquially, crap can mean ‘nonsense’ or ‘a lie’.

As a verb, it means ‘to defecate.’
- If your dog craps on the sidewalk, you should pick it up and put it in a bin.
Craps, always with the “s” on the end, is also a dice game where players gamble on the outcome of the roll.
- There were several people shooting craps in the casino.
Crap is also an adjective meaning ‘rubbish, no good,’
- That film was crap.
- I’m crap at maths.
It is used more often in the UK. In US English, the related adjective crappy is often used instead (you can also use crappy in UK English).
