hairodynamics 

(noun) The airflow in a car when driving with the windows rolled down. Can be good or bad.

My perfect hairodynamics setup is the driver's side backseat all the way down, with the driver and passenger windows cracked just a little bit.

Hydro-Dynamic Spatula

The Hydro-dynamic spatula is a spatula with port and starboard attachments and turbo drive. It appears in the episodes "Help Wanted" and "Sharks vs. Pods" and in the music video "Thank Gosh It's Monday." It also appears in the online game Anchovy Feeding Frenzy.

It has a normal spatula as a base but has two other spatulas attached to either side of it. Therefore, it is like a fork of three spatulas. There is a black stalk or areal on the top with a red L.E.D. light on top of that which flashes.

It has two known abilities: propelling the user skywards and having multiple spatula heads. Said multiple spatula heads enable the user to cook patties quicker and more efficiently.

"One hydro-dynamic spatula with port-and-starboard attachments, and let's not forget the turbo drive!" - Spongebob
