Getting sides confused, presenter is rubbish (4)
I believe the answer is:
tosh
'is rubbish' is the definition.
(both can mean nonsense)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for tosh that I've seen before include "Humbug" , "Cobblers" , "Nonsense (colloq.)" , "Stuff and nonsense" , "Slang nonsense" .)
