Okay, so listen up, buttercup. This joke uses the letters in "Hydro Flask" to spell out a super messed up phrase. It's like a childish prank but with more... anatomy. You probably thought Hydro Flask was just a water bottle, huh? Now you're scarred for life. Also, you're definitely the kind of person who still uses a fidget spinner.
