A straight guy who has a gay guy as a friend, and who has no problem with going to gay bars. Like a Fag Hag only male.

"He's his Stag Hag"
This has to be credited to Gimme, Gimme Gimme (BBC2 or 1), but proves be such a useful put down!!! Body Dismorphic Disorder (BDD) is, commonly, where a beautiful person looks in the mirror and sees a minger, swap donkey, bush pig staring back at them. Well, Reveral Body Dismorphic Disorder is where a hideously unattractive, usually overweight girl with particularly bad skin (it's my glands you see, nothing to do with the 18 Big Macs and 10 bars of family sized Galaxy I eat a day)looks into the mirror, and instead of seeing the bloated blob before her, sees a combined image of Catherine Zeta Jones and Angelina Jolie - therefore believing herself to be the epitome of beauty!!! Hence - Reversal Body Dismorphic Disorder
"Doctor, is it serious? I'm going to be on the front cover of Nuts, and can't keep the photographer waiting!!!"
"Well, you're five stone over weight and got skin like a pizza. I diagnose a severe case of Reversal Body Dismorphic Disorder. Fetch Gillian McKeith, nurse!"
