When your girls giving you head and when your about to finish, she sticks her finger in your asshole so you shoot like a fire hydrant.
Boy: "Last night I was getting head and she made me hydro pump."
Friend: "I WANT HER TO MAKE ME HYDRO PUMP!!!!"

Get the Hydromug. A water bottle that is beloved by the most annoying white bitches (vsco girl), and always carries it around with dear life saying SKSKSKS 24/7 and purposely drops it and says "and I oop-". These annoying fucktard bitches always cover the hydro flask with scrunchies and annoying stickers.
Regular person:"Hey what's up?"
Annoying white bitch:"OMG I just got my 8th hydro flask! I broke the other 7 by dropping them too much! SKSKSKS (purposely drops it) And I oop-SKSKSKSKS"
Regular person:"shut the fuck up"
