54-50

"No Police"

It appears to be a localized hybrid of 54 and 50 or fifty. It combines definitions of 54 (police radio lingo for 'no') and 50/Fifty (the slang term for police, as in "The 5-0", "Hawaii 5-0", or "the Fifty") to make "54-50" (pronounced "Fifty-four Fifty"). I keep hearing this term interspersed/interjected into the lyrics of local gangsta rap here in Baltimore.

"Bitches and niggas git outta my face (54-50....) dis is my crib, gonna bust your face (54-50...)"

to be a 50 pounder

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 50 pounder.
