1. The generally accepted term a group of more than one walrus (a glorious sea and land dwelling animal).
2. This also applies to the sexual technique dubbed "The Walrus". This technique involves ensnaring a lady friend and receiving oral sex from her. On the point of ejaculation the male comes in the girls mouth and punches her in the stomach (without removing his penis for 3 seconds). This forces his semen to froth from the lady's nose, forming tusks. As she moans from the punch to her stomach the male steps back and watches his own created walrus in all of its glory.
The "walrii" technique involves much the same motions except that two or more males must participate with an equal amount of ensnared lady friends at any given time.
1. Look at that glorious posse of walrii basking in the summer sun by the beach. It's majestic.
2. "Shit, me and Matt ensnared these two drunk girls last night. Pulled the walrii on them back at my place. You shoulda seen those cum tusks. She'll be smellin me for weeks!"
A cock suck in its most basic form is for a woman (or in some undesirable incidents, a man) to take a penis (cock) into their mouths and suck it. There are many variables on this technique (see "walrus" and more).
"This one bitch was really drunk and I carried her about all night. I was getting a bit sick of her and everyone fucked off leaving just the two of us. I laid her down on her knees and said 'You owe me this'. Some might say that was a form of rape, but hell, what a fuckin cock suck"
