Throw out travel game (5)
I believe the answer is:
bingo
'game' is the definition.
(bingo is a kind of game)
'throw out travel' is the wordplay.
'throw out' becomes 'bin' (**).
'travel' becomes 'go' ('go' can be a synonym of 'travel').
'bin'+'go'='BINGO'
(Other definitions for bingo that I've seen before include "Popular gambling game in which numbers are called at random" , "House!" , "Cry on discovering something" , "Lotto" , "Housey-housey" .)
