When you approach the female for anal, she turns around looks at you and eagerly nods her head up and down like flipper while emitting a shrill eh-huh, eh-huh pleased noise
I took this girl home last night and gave her the ol happy dolphin.

The act of ramming your erect member into a females anus. The noise the female emits often resembles the "Indo-Pacific Bottlenose Dolphin", which inhabit temperate to moderately warm waters of the Northern Pacific Ridge. For more information visit your local library.
The Poster above clearly doesn't know what a Happy Dolphin Is.

when performing the act of sex in a doggy style position the male takes both of the bitch's wrists and pulls back on them making the broad look like flipper begging for a treat.
I was plowing this swamp donkey from behind and was pulling her hair to gain leverage... that did not get the desired depth so i took her by the wrists and pulled her upright with every pull she resembled a happy dolphin making that weird noise and everything.... She told me it was the first time shes ever been filled out before...
