huh

when someone is trying to sound smartass or doesnt care and wants to be extra infuriating and wants to sound smart

Often fake friends use it because they dont care.

Also people who want to get a rise out of you in a argument say huh because they think they are better and will get a rise out of you.

Person 1: hey bro why were you talking shit about me behind my back? like what the fuk i thought we were friends.
Person 2: huh
Person 1: YOU HEARD EXACTLY WHAT I SAID ARE YOU STUPID?!
Person 2: huh

Example of when they dont care:
Person 1: Ima be honest I've been severely depressed for the last year and want to commit but idk if i should.
Person 2: huh
Person 1: BRUH I swear if you say huh one more time i will take you with me.
Person 1: THATS IT MOTHERFUKA IM TAKING YOU WITH ME TO THE GATES OF THE UNDERWORLD
