There was a question asking for the collective noun for shrimp. Collective nouns are things like a gaggle of geese broadly meaning a group. The collective for shrimps is troup, sometimes with an 'e' on the end - take your pick. The plural of shrimp is shrimp or shrimps.

There's a vulgar(?)( meaning of shrim as a verb meaning toe sucking (as allegedly David Mellor and Antonia de Sancha some years ago)
