Noun: A creature of Welsh origin that can often be found rolling around the gutters of London's fashionable Soho district on Tuesday & Friday nights. Can be identified by its distinct features, so horrific they often cause severe vomitting upon sight. If seen wearing pink underpants caution is advised as it is likely to be so intoxicated it will have been rolling around in gutters and may hiss violently if approached. It has an utter fascination with the Orient and can often be found with a mouth full of Thai or Chinese.
oh my, that Hissing Troll is an utter disgrace!
