Stuck with dull type (4)
I believe the answer is:
bore
'stuck' is the definition.
(stick and bore can both mean to pierce or skewer)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bore that I've seen before include "Tedious person; steep wave" , "Capable of being shifted" , "Push through a crowd" , "Tedious thing" , "Tedious person - wave - make a hole" .)
