One time in high school, I heard somebody yell “Steve, you [bundle of sticks], stop talking to your girlfriend and let’s go!” and Steve was in fact at the time talking to his girlfriend.

Fag evolved into something completely different in the '00s, and was seldomly used to imply homosexuality. I don’t know how it happened, exactly, but it was seemingly repurposed to mean loser/douchebag, just as gay was used to express something being lame. This didn’t stop the words from being offensive, but it was still an interesting change of definition. Obviously they’ve since reverted.
