Jul 12 Word of the Day
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

Mindfuck- The process of raping someone's intelligence and/or beliefs with lies and manipulation. The only defense is instinct and intuition; otherwise known as the TRUTH.
Man: Are you crazy??? I would never fuck my ex-girlfriend! She's my ex for a reason!

Woman: Then why did she text you "I had fun riding your cock last night", when you told me you were taking your grandpa to the doctor?

Man: Because she's crazy baby. She's just jealous.

Woman: STOP trying to mindfuck me!

to forcibly expose a person to an idea or lesson that leaves he or she, dazed and awestruck, to go through a bout of depression that lasts a variable amount of time in which they question existence, religion, and what they themselves would do in hypothetical situations. Usually the said person will ponder these questions at all hours of the night because they can not sleep and will end up finding only a few answers/revelations. Once of which may include that "if" is the most evil word in the English language. Eventually he or she recovers & usually feels a mixture of a hate & love toward the mind-fucker. Hate for their mental/emotional anguish and love for the perspective they gained and the lesson they learned.
Dude, I totally got mind-fucked by one of Ellen Hopkins books the other day.
