When you masterbate so much you develop a calis on the head of your penis and then don't shower for a while and go and bone.

a drug that can seriously mess you up. some say it comes from the eggs shells of turtles from madagacar so that's why it's so hard to get, but others claim it's made by heating up a very rare certain type of fungus, one that when it is heated, takes a form similar to that of the shell of a turtle. taking one turtle shell can greatly increase dopamine uptake in the brain and send the user on an unbelievable trip. there are no known addictive properties, however there can be damaging long-term effects to the brain and CNS.
Man, I did turtle shells last week, and it was the most insane trip I have ever been on...I was absolutely shell-shocked.

There is nothing to describe about this drug, because many people do not survive the trip, but for the ones who do, they say it is the craziest shit theyve ever done. Don't even try to find the drug because it is only found on 3 beaches in madagascar where leatherback turtles lay their eggs exposed to sunlight, which is what makes the drug so powerful.

When your balls shrivel up into your abdomen, leaving the scrotum looking like a ridge-textured turtle shell. This is commonly caused by either exposure to cold or in those situations that give you the willies, much like goosebumps.

A turtle shell is when your dick is so shriveled and soft that it is practically retracting back into you, similar to how a turtle goes into its shell. A turtle shell usually occurs after you have just ejaculated or after you get out of water.
