Ribbed southern press chief after meal (6)
I believe the answer is:
teased
'ribbed' is the definition.
(I've seen this before)
'southern press chief after meal' is the wordplay.
'southern' becomes 's' (abbreviation).
'press chief' becomes 'ed' (I've seen this in other clues).
'after' says to put letters next to each other.
'meal' becomes 'tea' (tea is a kind of meal).
's'+'ed'='sed'
'sed' after 'tea' is 'TEASED'.
(Other definitions for teased that I've seen before include "Made mild fun of, bantered" , "Gently ribbed" , "Separated fibres - ragged" , "Tantalized" , "Subjected to banter" .)
