Chaffed, teased (6)
I believe the answer is:
kidded
I believe this is a double definition.
'chaffed' is the first definition.
('kid' can be a synonym of 'chaff')
'teased' is the second definition.
(kidding is a kind of teasing)
(Other definitions for kidded that I've seen before include "Chaffed - teased" , "Joshed, teased" , "Joked or teased, like young goat" , "Teased gently, deceived" .)
