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.

hydrodynamiccockthruster 

A hydrodynamiccockthruster lurks in the shadows of the night, thirstfully awaiting his victims as they unsuspectinglly stroll past. He is a hunter and gatherer, a saint amongst feeble minds. Arched back ready to pounce with erect cock holstered at the ready.
