Drawing topless and teasing about (7)
I believe the answer is:
ragging
'teasing about' is the definition.
'ragging' can be an answer for 'teasing' ('rag' can be a synonym of 'tease'). I'm not sure about the 'about' bit.
'drawing topless' is the wordplay.
'drawing' becomes 'dragging' ('drag' can be a synonym of 'draw').
'topless' means to remove the first letter.
'dragging' with its initial letter taken away is 'RAGGING'.
'and' acts as a link.
Can you help me to learn more?
(Another definition for ragging that I've seen is " Teasing, joshing".)
