Thrusting attempt by Crosby (8)

I believe the answer is:

stabbing

'thrusting' is the definition.
(stabbing is a kind of thrusting)

'attempt by crosby' is the wordplay.
'attempt' becomes 'stab' (I've seen this before).
'by' says to put letters next to each other.
'crosby' becomes 'bing' (bing crosby).
'stab'+'bing'='STABBING'

(Another definition for stabbing that I've seen is " (Of pain) causing a sharp sensation".)

I've seen this clue in The Telegraph.
