Get the scasm mug.
The orgasmic feeling you get when you pick scabs.
Picking Ross' scabs from his chafed inner thighs gave him a massive Scasm. He then proceeded to put them in his sandwiches for tomorrow's lunch. Yummmy!

Get the Scasm mug.
An orgasmic feeling you get when you pick the scabs on the inside of your nose.
Nose-scasm's are the only things that get me through watching an episode of Keeping Up With The Karshitians.
