Crafts that guys do, but don't call crafts since that would be really gay; for example: building bongs, modding Xboxes, arcade video game restoration, making leather goods (but that is kinda gay if it's black leather), woodworking, modding and upgrading engines and cars, etc.
Randal: "I like crafts, like building bongs."
Jason: "Dude! That sounds so homo!!!!!!!!"
Randal: "Hey, I like mancrafts..."
Jason: "If you put it that way, I guess that would be really cool! I know tons of guys...I'll call them all up so all us guys can get together for mancrafts. No women!!!!!!!"
