That pimp with a suit and a mask on
Lil B may refer to pimps and their coldness regarding their everyday work — degrading the sexuality and dignity of women without any remorse or regret.
However, he may also refer to those “corporate ass ho[es]” mentioned in the line earlier — greedy capitalists whose only concern is to make as much money as possible, leaving behind poverty, injustice and environmental destruction. They treat the Earth and its inhabitants like bitches, thus pimping us all — the mask is not meant literally but alludes to the hypocrisy of all those people in power: Nice in front of the camera, scumbags as soon as they’re off; nice to the people, but backstabbing them as soon as they have the ability to.
