when someone “gets hitchhiked” it basically means that they got thumb-fucked in their vagina. instead of getting fingered with the pointer/middle finger, the person fingering them opted to use their thumb instead. this comes from the known-symbol for hitchhiking—a thumbs up.
person #1: “dude i got hitchhiked last night…”
person #2: “damn he used his thumb? that’s crazy.”
person #1: “yeah i woke up bleeding.”
