Attempt to fuck

When a fuck has gone wrong due to several different possibilities (i.e. whiskey dick, no condom etc.)
"You're usually DTF but it turns into a ATF."

"Yeah, she was DTF but we didn't have a condom and she didn't want to pull out so it turned into an ATF"

ATF stands for alochol tobbaco and firearms agency, if you Have ever heard about that disaster in waco,Texas where that religous cult leader David koresh held up childern and his folowers in a bible school for a couple of days, and had a big shoot with automatic weapons with the ATF. The reason this whole situation went bad was that a ATF spy's cover was blown so david was ready for the ATF, and The buliding ended up burning to the ground. ATF sure fucked that one up.
hey did you hear about that shoot out with the ATF in texas a couple of years ago.
