onetimeacraft 

One of the best blacksmiths out there (In roblox only). He will join you in making your game and then over time go into hibernation like those lizards and snakes and shit. Once in a while he pops up and shows old memes and then disappears again.

This guy is a onetimeacraft.
Kids! Stay away from him! He's a onetimeacraft.
I dream of becoming a onetimeacraft.

woodbury onetime 

The act of banging a chick in the dark and then pulling a switcheroo where one partner leaves and then another comes back to take over. With NO knowledge by the victim.

I once pulled a Woodbury Onetime by fucking a chick in the dark, and in the middle, I pulled out, switched with a buddy, and he finished up without the chick ever knowing.
