A character from the SNL line up of back in the day. He'd knock on the door and say a phrase to convince the party on the other side of the door to answer. For example knock knock
"Knock knock" (actor on other side of door) "Who's there" The landshark then answers, "Pizza man" then the actor on other side of door would open the door and get eaten by the landshark

The result of being caught on the toilet, taking a shit, when you realize their is no toilet paper. So you leave your seat with your underwear half mast and race to the other bathroom in the house to wipe your ass - dropping small, sticky pieces of shit, that were attached to your cornhole, behind you all over the house - or land sharks.
I was dropping a grogan when the JWs came and knocked on my door. I thought it was the mail guy so I hurried up to wipe, but discovered I was all out of the good stuff. So I made a mad dash to the other bathroom and totally left a land shark in the front hallway.

This is a term that is used when referencing the act of having sex with a woman while she's on her period. Sharks attack women who are menstruating in the ocean, and since you are having sex with a woman's bleeding vagina on the land, it is called 'land sharking'. It can also be called a 'shark attack' and is often accompanied by the Jaws theme song and a hand smacking motion immitating the clamping of sharks' jaws.

This should only be attempted if...
A) one is extremely horny
B) one is extremely commited
C) one is both extremely horny and extremely commited
Latisha's on her period, but I'm so damn horny. I think I might land shark her anyway.
