Was supposed to go to Bangkok
Until she figured out that she don't really like to bang cock

from Tyler The Creator – Jack and the Beanstalk Lyrics on Rap Genius

Meaning

Let’s be honest — this homophone is what runs through every guy’s mind when we hear “Bangkok”

Bangkok is the capital city of Thailand. It is huge (605 square miles) and is home to over 9 million residents. It is also one of the “hottest” vacation spots because of its deep cultural roots, a plethora of both traditional and modern entertainment, and an abundance of five-star resorts.

But unfortunately, Tyler’s wondrous vacation plans were ruined when his girl found out that she swings the other way (if she doesn’t like to “bang cock,” then there is only one real alternative) — in other words she’s a lesbian.

(I don’t see why you would drop your plans… take her there and find her a girlfriend and you both will be happier than you ever were in your relationship)

Also, He’s referencing the whole Milan thing. Milan was one of Tyler’s ex’s who turned lesbian after dating Tyler.
