A little sticky, and in bad taste (5)
I believe the answer is:
tacky
'in bad taste' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tacky that I've seen before include "Sticky; showing poor taste" , "Cheap and nasty" , "Vulgar - viscous" , "Showing poor taste or quality" , "Tawdry" .)
