From The Walking Dead. Is said by Abraham in the most badass scene ever.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

An extremely powerfull word used to describe the state of a person's 'Dickness' or 'Dick-being'.

a word randomly blurted by an angry Mexican girl. HAHA just fuckin. Nah, it's an angry phrase used only when flustered and you place it in the middle of many curse words of your choosing. You don't go around calling people a mother dick cus that's just dumb.

When a normally strict catholic girl gets incredibly frustrated and tries to use bad language. Not being used to it, she'll combine insults she's heard - in this instace: Motherfucker & Dickhead. Motherdick.
