Clawgasm 

The horrible sensation that a woman experiences when her sexual partner has long, dirty finger nails.

He didn't clean his teeth or shower, but the worst part came when he gave me a clawgasm

The excitement of handling clay to an extent where one over excites them self resulting in an orgasm. Can also occur when wedging, glazing or wet sanding.

Dude, working with the clay was soooo amazing I almost had a claygasm.
