Fuckin’ problems.

Ubiquitous rapper 2 Chainz was booked at LAX last night for possession of promethazine – or sizzurp, as it’s known to the rest of us.

Narcotics officers also found a small quantity of weed on the rapper.

It’s hard to imagine how the cops knew to swoop on him, but this tweet, posted not long after the robbery, might’ve given them a clue:

Rule# 3 we definitely got geeked up in San Fran , best smoke in the world. 2 blessed 2 stress

It’s been a bad week so far for 2 Chainz – the arrest comes a day after he was robbed at gunpoint in broad daylight in San Francisco.
