This is a curse word used in Jamaica when surprised, angry etc. It is apart of the language Patios. You can say it is "equivalent" to fuck.
In Patios: Yuh nuh see me a study?! Tun down the bomboclaat music!
English: Can't you see that I'm studying? Turn the fucking music down!

In Patios: Bomboclaat dawg, yuh hawt!
English: Damn nigga you look good!

Jamaican patios expletive used to express surprise or disdain. Used in a similar way to 'fuck' in English.

The literal translation is bum cloth. I.E. something that you wipe your bum with after having a shit. It has the same meaning as raasclaat (arse cloth) and is similar to bloodclot or pussyclot (blood cloth and pussy cloth respectively), both meaning sanitary pad.
Wha de bomboclaat?

Grown from Jamaican origin, this word would be used as an reaction, or an expletive.

Most commonly incorrectly used on twitter posts by white and uncultured people as a form of “add caption” or “explain this picture” which is wrong.
