someone or somthing that believes that TOOL has the most powerfull and moving music. Also they follow the ways of Maynard James Keenan in believing that "...music isn't all about the lyrics but also about the music itself, otherwise people would be selling out with spoken word tours. The music carries the emotion, the lyrics help define where that emotion is going"-MJK.
It's tool+charismatic, with a huge hint of sarcasm. It describes when a somewhat attractive toolish person who self-denies and/or is unaware of the fact that he/she is a tool seeks attention/support through social media or/and other public platforms, and intendes to manipulate others' judgments with his/her "covert" toolishness.
X (referring to a gal X's involved with): Dude, she's throwing a rant complaining about abc again on Facebook again.
Y: Meh, such a toolismatic attention seeker. Honestly, no one gives a hoot.
X: EXACTLY.
