I believe the answer is:
taunt

'tease' is the first definition.
(I know that tease can be written as taunt)
'bait' is the second definition.
(I know that bait can be written as taunt)
(Other definitions for taunt that I've seen before include "Make fun of" , "Mock, jeer" , "Sarcastic challenge" , "Bait with insulting remarks" , "Goad, provoke" .)
