Hi,

Is there any word that can best describe a person who likes to make fun of others?

Depending on the context, 'make fun of others' can have eithera positive/friendly or negative/unkind feeling to it. eg

positive - kidder, prankster

negative - sneerer, bully

I assume you asking for nouns and not adjectives or verbs, of which there are many.

Teaser would apply if he is making fun of people in their presence.

A polite term is: mickey taker. Someone who 'takes the mick', or 'takes the mickey' is someone who makes fun of others.

Hello,

Clown is one of th word we uses the persons who likes to make fun of others.

Hi,

I wouldn't say a clown makes fun of others. A clown is someone who likes to do funny things.
