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 ascam and his greatest achievement was only to be a 50 pounder.
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
May I have an order of regular degular buttermilk pancakes? Without all the added jazz? Hold the blueberry smiley face, strawberry glaze, chocolate chips and whipped cream.
