So there's this douchebag(not the cool douchebag, the wannabe douchebag) in a class of mine and he's ALWAYS crying out for attention. Nearly everyday he acts insecure and tries to bring me down, saying stuff like "Change your clothes", "You are a faggot", "I'm cooler than you are" etc. Whenever he says this every other beta gets involved and tries to egg me on "Kick his ass", "Bitch him out" etc.

So guys, please tell me how to deal with this?

I dont know how you reply to these remarks, hopefully your not just sitting there taking shit, but you have two options.

1. Dont let it phase you at all, and reply with a smooth funny come back every time. E.g "your a faggot", reply with "you wouldnt be alive right now if that were true" or "Change your clothes", with " why can you still see your mothers cum stains from last night?"... doesnt have to be that harsh but you get my point lol. Try to do it around people too, make him embarrassed, and
trust me he will eventually stop if he keeps getting burned. This may lead to confrontation so be prepared.

2. If you cant think of something clever, just straight up stand up to him when you see him alone. Go with a friend or two if you can and ask him what his problem is..... and that he needs to shut the fuck up and take his insecurities out elsewhere.... Dont let ANYONE bring you down, even if it means getting hurt in the process, just show you have the courage to stand up for yourself and it probably wont even get that far. He will stop once you show some balls.

and 3 which is dont recommend at all is to sit there and take his shit, hoping one day it will stop. Which will probably lead to self esteem issues later in your life, then you'll have to deal with those and its a fucked up cycle which you should to avoid to live a happy life.

I've dealt with these kinds of kids when i was younger and number 1 or 2 will guarantee to shut him up. Hell, there were kids that tried this shit with me and once i showed that i wasnt scared of effected , they started to respect me, and i actually ended up becoming best friends with the biggest shit talker in my class.

All in all...DONT SHOW YOUR PHASED AND DONT SHOW YOUR SCARED, stand up for yourself and it will stop.

Good luck and let me know how it goes
