If you just want to make him go mad and not hurt him then simply tell him that you went out with another guy who is a friend and say something good about him.. That's enough to make a guy go mad...
How To Make My Boyfriend Mad?
Get all dolled up,you know, make up hair, casual jeans & cute shirt. And just hang around your own house with "much to do about nothing attitude"... Don't be in the mood to have him pawing on you this time. And trust me he will find a reason even if its unreasonable to be mad. Good luck, I guess!!!
