Fat-fall

When a fat person falls down onto a couch instead of gently easing them self onto it because their legs can't support their weight on the way down.

Your grandfather just fat-falled onto the couch and broke it.

Carbon Curbstomp

A carbon curbstomp is the mark you leave when you don't give a shit about the environment.

Al: "Your carbon footprint will be through the roof if you drive that Hummer."

Me: "Carbon footprint? I don't give a SHIT about the environment. I'll leave a carbon curbstomp."

Bowltending

When you push your cereal down below the milk line to make it sure it isn't dry when you eat it.

Without bowltending, this cereal would be so dry.
