To describe a noun or pronoun that is as awesome as cats, which are clearly very awesome indeed.

Typically used to express one's appreciation after having witnessed an impressive display of skill, or to impress upon others the level of one's own skill.

Especially applicable to anything which involves a high degree of dexterity, mental focus and cat-like reflexes.
"Yo, did you see that Danny MacAskill bicycle trick video? Dude is mad catsome!"

"Shit yeah, I just got a 25 kill streak in Call of Duty! I'm wicked catsome!"

The horrible moment when you realise that you have accidentally done something very slightly wrong which has very bad (usually embarassing) implications for you. This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.
Message: "i'm free this afternoon so come over and fuck me senseless, my parents will be out all day"
Recipient: Mum
