Which meaning does "little" have here?

"Little" here means "insignificant". Ross is saying that Chandler's "jokes" are meaningless and unimportant by calling them "little". This is a way "little" can be used. Keep in mind that using "little" in this way can be seen as confrontational or rude. Ex: I don't like all of the little comments you make towards me.
