Apart from the plethora of UK colloquial slang, the only single verb I can think of that I still see regularly in books or hear in conversation is;

Mock

to criticize and laugh at (someone or something) for being bad, worthless, or unimportant

 

to laugh at or make fun of (someone or something) especially by copying an action or a way of behaving or speaking

"They continue to mock the idea of a new government"

For something a little more light hearted;

Jest

something said or done to cause laughter

 

an utterance (as a jeer or quip) intended to be taken as mockery or humour

"you should know that our teasing was done entirely in jest"
