6a OHMS

[chokkie]

Thank you so much everyone. It's obviously "half-nelson", as 6a is OHMS.

Appreciate your help.

Chox.

Definitely half nelson: anagram of fallen and nosh (= tuck).

I think 6a is ohms: resistance and also short for 'on her majesty's service'.

[rudiboese]

Half Nelson. Tuck up = Nosh and anagram of fallen.
