Terribly lame set of courses (4)
I believe the answer is:
meal
'set of courses' is the definition.
(I've seen this in another clue)
'terribly lame' is the wordplay.
'terribly' is an anagram indicator.
'lame' anagrammed gives 'MEAL'.
(Other definitions for meal that I've seen before include "Eg, dinner or tea" , "Repast" , "Breakfast, lunch or dinner" , "dinner, maybe" , "Breakfast, dinner or supper" .)
