A portmanteau of the
words "shit" and "strangle" (a la "slithy" or "
mimsy") meaning to strangle someone with such
force, you poop your pants.
"Remember that German girl I
met at the bar last night? When we got to her dorm room, she wanted me to shrangle her..."
"Well, did you?"
"Fuck
yeah I did! But I straight up destroyed the
sheets on her bed..."
