(Almost Gay Best Friend Forever)

Mainly male friends (but females can be this too) who act gay or feminine (or masculine, depending) but are in fact straight.
"Did you see my new sweater, and my jeans, I got them on sale at Pac Sun for like $25 all together, and Sara, LOOK AT THESE SHOES, LOOK AT THESE MONK STRAP SHOES, I WANT THEM SARA, THEY'LL GO SO WELL WITH WHAT I WEAR, AND THEY'RE SO CLASSY, but they're $500-$1000."

"Oh Greg, you really are my AGBFF."
