This is a very common and popularized word which comes from the root: beurk.
This phrase is commonly used to replace any insult and is only looked upon in bad context.
It is a word that should only be used if need be, frankly its just not a nice thing to say.
The term can also be altered depending on the situation , such as :
Im going to burke you!
what a f*ckin Burke
Stop Burking like that.
Dont be a burke.
F*ck you, Burke.
You are Burking all over the place...its disgusting.
