You are full of shit jackie

Tell txtittyfag to go fuck himself.

Brilliant answer Woodwolck67!

Bang 69 has it correct. or just walk away.
It is highly unlikely a gay person would hit on you unless you are someplace where that regularly happens. Why court conflict? Is your male ego so shaky that you need to get violent on a stranger. Would want to get hit if you were flirting with a lesbian?
I would want to be told not interested and both walk away.

Stab the faggot to death like this rapper did:

Pet his guide dog.

If a faggot was flirting with me, I'd tell him, "Hey, MackTruck, I appreciate your offer of BBBJTCWS, but I only like girls and real dolls".

Tell them there is a surprise for them under the hood of the truck. Get them to crawl inside by the engine. Tell them it's next to the air compressor. Then let loose with the air horns They'll tell you it's the best blow job they ever got.
