Just tell her. Let's see how funny your brother thinks it is once you do that.

lmao

Wow that kid is a jerk

i usually dont endorse outing gays without their support but **** him if hes gonna be a douche

Come up with some kind of epically embarrassing way to reveal your brother's sexual orientation to your parents. A simple way could be to respond that you tried, but your brother said she wasn't manly enough. More entertaining would be to get a girl to come over on a 'blind' date. Then, have her look at your brother, say something along the lines of "You set me up with the fag!?" then some swear words at you before storming out.

how about you give him a helping hand out of the closet an tell her

Wow, your mom is a total bitch. Just 'cause she wants you to get him a girlfriend, she gets mad at you? That is some stupid logic.

Yeah seriously. Either way, it's not your problem whether or not he has a boy/girlfreind. And if he's fonna be an ass about it, tell her that he's gay. Problem solved.

just find him a girlfriend and let him deal with it/her

its not your job to find your brother a person. Don't know about you but my parents stayed away from match making. Thank goodness. If he's gonna be a douche about it, then out him. Serves him right.
