Someone who is scared of trumping.
A human being that refuses to trump during the day due to public shame or belief that they are not an animal, resulting in a collection of trumps being stored up inside them.
During the night the human being "deflates", passing wind throughout their sleep and the trump collection leaves their body. For this reason the trump collector will never be satisfied with their collection and wake up the next day striving to build up their collection again.
Dave "You know what, I've never heard you trump George..."
George "Thats because I dont!!"
Dave "Ah right, it's you. You're The Trump Collector"
