Wu Tang's Ghostface Killah The Guy Who Bought Our Album Is a Wonky Michael Jackson!

EXCLUSIVE

Ghostface Killah isn't done trashing 'Pharma Bro' Martin Shkreli ... the guy who plunked down $2 mil for the Wu Tang one-of-a-kind album. 

Killah and another Wu-Tang member were out at LA Live Friday night and he has a new nickname for the AIDS/cancer drug gauger ... a nickname that cuts like a knife.
