<human>: Hello Reddit, we have a problem and we'll call him H.

I'm in a friend group of 6 people who met on Facebook on one of those college class pages because we all had similar interests in sports, partying, etc. and we're all heading into our freshman year of college this fall. We've all talked and hung out this entire summer and even made a weekend trip to a beach resort for an amazing weekend. The entire group is awesome, except one of the group members (H) tends to get too sensitive when we make jokes that relate to him. Remember, we are all 18 year old males and love ripping each other occasionally all in good fun, it's what friends do. It's just joking around, nothing we say or do is meant to harm anyone in anyway and we've established that besides H. H can love making jokes about others but the minute someone makes a joke about him he immediately kills all fun, gets angry and defensive, and starts threatening us to stop. 

Don't get me wrong, he's a great guy to hang out with when all is fine and dandy but the minute something is said about him he changes into a super pissy person and we have to begin apologizing to get him out of this mood. My question is on behalf of our group, how do we deal with him? We love hanging out with him most of the time but when he's in this mood he's the ultimate buzzkill.

Also a quick note, he's going to be the roommate of one of the other guys in the group who's awesome so we can't ditch him nor do we want to. Even the roommate says H is way too oversensitive in terms of this stuff.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Friend gets in a super sensitive mood once our group roasting shifts to towards him; we want to convince him to lighten up a bit and not take things so seriously like all the other members of the group
