It is used when taking 3 or so Ritalin tablets in one day is just too much of a pain in the ass and you want to just have one dose and have it remain steady throughout the day. Doses come in 18mg(baige), 27mg(blue), 36mg(white), and 54mg(red) cylindrical tablets. It is the second step down from Adderall(amphetamine-dextroamphetamine) in treating ADD/ADHD.

conception

an act of inception (planting an idea in ones mind) performed through an indirect mindfuck.

While dreaming if sounds from other people having sex (through a wall or in another room) infiltrate and start controlling your dream, an act of conception has been performed on you.

concert vagina

The concert vagina is a woman who pretends to be one of the guys in order to get attention from a group of single and/or "unavailable" men in situations where the female/girlfriend element is intentionally absent. Akin to a concert pianist, a concert vagina earns this title by consistently positioning herself at center stage in a group of enthralled spectators.

Trademark moves of the concert vagina include inviting herself to poker night and showing up in a miniskirt holding a six pack of your favorite beer. In this manner, the concert vagina is able to advertise herself as the best of both worlds. Don't you wish your girlfriend was hot like the concert vagina?
