When you're fucking your significant other in the cowgirl position while talking dirty to them through a speak and spell
Me and stacy tried the dirty hawking last night I was like "oh... yeah... baby...."
When you're doing a girl from behind in the ass. You then squall that an eagle.
"Bro, Lisa let me Dirty Hawk her last night."
"Bro, the Dirty Hawk?"
"Yeah bro, I squalled so loud the neighbors heard me."
