Boisterous or uproarious (7)
I believe the answer is:
riotous
I believe this is a double definition.
'boisterous' is the first definition.
(thesaurus)
'uproarious' is the second definition.

(Other definitions for riotous that I've seen before include "Behaving wildly" , "Marked by public disorder" , "Unruly U rebellious" , "Boisterous and unrestrained" , "Unrestrained, wild living perhaps" .)
