I'm a little stuck... Click here to teach me more about this clue!

This clue might be a double definition.

'it's nonsense' is the first definition.
(tosh is a kind of nonsense)

'mate' is the second definition.

Can you help me to learn more?

(Other definitions for tosh that I've seen before include "Scottish chum" , "Baloney, twaddle" , "[BLAH]" , "Stuff and nonsense" , "13 [TRIPE]" .)

I've seen this clue in the Evening Standard.
