Make fun of his mom or his package or basically anything that he is either overconfident about or insecure about.
Example: If he is a good football player, bother him about the one time he failed. Or if he's bad a football, just stress how important football is in measuring a man's worth.
Btw, irritating a man should only be done if you have a good motive. You need to be very strategic too.
Good luck.
Detail pls ,
What guy? Boy friend, male boss, uncle, postman etc?

Wow, I really hate to see my ex with other man (rich, more handsome, popular, etc make me more ‘panas’).
My (male) friend makes iklan surat kabar in obituary section… I don’t know his ex girlfriend feel about it.
If you more successful than him, he also can irritate… you know man with ego.
The greatest element in a man is his dignity of being one.
Depleet him of that honour by immasculating him in front of either his male friends and possible girlfriends.
This way he looses his alpha male position and you win by virtue.
Oh!! Who let you down in love... haha. Well! I think you don´t have to do anything, that´s exactly what is gonna irritate him more, Maybe he still feels something about you, so... You have just to act normal!! Let him see that you don´t care because you´re beautiful enough to get a new guy better than him.
Live your life and... Enjoy!!
