Toboggan filled with funny things (7)
I believe the answer is:
luggage
'things' is the definition.
(thesaurus)
'toboggan filled with funny' is the wordplay.
'toboggan' becomes 'luge' (synonyms).
'filled with' indicates putting letters inside.
'funny' becomes 'gag' (a joke or gag can be called a funny).
'luge' placed around 'gag' is 'LUGGAGE'.
(Other definitions for luggage that I've seen before include "Belongings" , "(Traveller's) suitcases" , "Impedimenta" , "Travel bags" , "Cases etc for travel" .)
