Spoofing may be the act of pretending to blowing coke up someone's butt, but then "accidentally" snorting it yourself.

Samantha: Woah, easy now. It's my turn!

Samantha: WTF, Dave?! Freeloading as always, now you fucking spoofed me???

I know about boofing, I learned about it during one of the more recent us supreme court confirmation hearings

Spoof is a slang term used in certain parts of the world that refers to a certain viscous liquid.
