When one fucks a fat chick at the beach, and proceeds to dip his moist penis into the sand, then putting it back into the vagina, making the seal bark!
German:dude, what's with the hand print across your face?
George: I just got back fromthe beach with Grace... And gave her the Barking Seal! It didn't go well with her
1) The sound, during sex of any kind that involves a phallus (organic or otherwise), made by its quick (& sometimes painful) ejection from the cavity in which it was plunging. The resultant 'POP!' when echoed inside the cavity, is the baritone seal. The POP is, much like a freshly-opened pickle jar, the breaking of the seal.
2) The seal-like moaning sounds made, usually accompanied by sealion-esque bucking and thrashing, by certain types of sexual partners nearing orgasm.
1) "I was getting deepthroated by Theresa last night when I got excited and slipped out--you should have heard the baritone seal it made, bro! Sounded like a hotdog bustin in a microwave!"
2) Yo, I tried to hook up wit Robin last night, but she started letting out baritone seals when I went down on her--bitch was putting on a Sea World show, dawg!
Barbeque Sauce and Steak Sauce are contradictions to each other. Something that is Steak Sauce is something that is utterly amazing and totally awesome. Barbeque Sauce is something that is god awful.
