A 50 pounder is a consultant or advisor that gives unsolicited and useless advice, with the ulterior motive of getting paid for his apparently "quality" services. He is a salesperson, good with words, that can trick a naive person.
The 50 pounder is actually skint and has very little money in their bank account (about £50). When confronted, the 50 pounder gets aggressive due to his/her fear of being exposed.
To be avoided via good bullshit detectors and due diligence.
Dude, stop talking to him. He's a scam and his greatest achievement was only to be a 50pounder.
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
