"Dude, my girlfriend finally let me boomslang her last night."
"How was it?"
"She almost died..."

1) One of the coolest and scariest snakes in Africa. It venom kills by thinning out the blood, and makes bite victims bleed from every orifice in their body, including eye-sockets.

2)A snake that can kill a grown man with 4mg or less venom.

3) A snake that some total ass-hats keep as a "pet."
I wouldn't hand a boomslang to my worst enemy. Wait. Yes I would.

While a man is standing up and receiving oral he suddenly pulls out, spins around in a circle, and whacks her in the face with his member leaving a penis length mark on the side of her cheek and then yells, "BOOMSLANG, BITCH!!"
I was out with my girlfriend last night and she was giving me this great blowjob and then I totally boomslanged her. She still has the marks.
