packing shit
A fancy way to say you're getting butt-fucked, and it's probably the best thing that's ever happened to you.
My cousin said, 'I got packing shit at the party, and it was amazing.'
He texted me, 'I got packing shit by the pool, and now I'm sore.'
She said, 'I got packing shit by my ex, and it was worth it.'
