Rhyming slang for "hungry".
The phrase "Paulson" is a contemporary twist on the classic cockney rhyming slang of Hank Marvin
or "Hank", which is slang for "starving".
"Paulson" abstracts "Hank" to a further well known individual: Henry Merritt "Hank" Paulson, Jr., the 74th US Treasury Secretary and once CEO of Goldman Sachs.
Where one would previously say "Hank", they might now say "Paulson".
Brett mate, lets grab some toast already. I'm freakin' paulson!
