What might persuade a couple of Romeos into bed? (6)

I believe the answer is:
carrot
'what might persuade' is the definition.
I can't judge whether this defines the answer.
'a couple of romeos into bed?' is the wordplay.
'couple of' indicates the doubling of some letters.
'romeos' becomes 'r' (this could be a standard abbreviation I've not previously seen).
'into' means one lot of letters goes inside another.
'bed?' becomes 'cot' (cot is a type of bed).
'r' doubled is 'rr'.
'a'+'rr'='arr'
'arr' going into 'cot' is 'CARROT'.
Can you help me to learn more?
(Other definitions for carrot that I've seen before include "Vegetable - incentive" , "Orange vegetable" , "The vegetable for persuasion" , "Red vegetable used as inducement" , "Tapering vegetable" .)
