The overly annoying friend who becomes pissed off whenever your significant other is present, and for no apparent reason. The boyfriend bitcher is friends with both people in the relationship, however, is not a big fan of the relationship itself, and makes it known to both parties in obnoxious and bitchy ways.
Boyfriend Bitcher - "So Kathy, those new shoes are so blah blah blah, you're such a good friend, blah blah blah"

(significant other approaches)

Bitcher - (rolls eyes) oh. whatever

Boyfriend Bitcher - "So Steve, i love being your friend blah blah blah"

(Kathy approaches)

Bitcher - (rolls eyes) I can't deal with you two.
