Shushh

A word used in occasions when the person literally has no insults and small personality. They may use it to shutup the other person for saying something mean, or true, but the opponent that may use the shushh is likely losing (if in an argument) and has no defence. Basic loser
It is common for the 'shushh' -er to be combined with the haha but in which case, is not actually funny.

Roadman may occasionally use this, but it can be used properly with intellect.
