A phrase used by men, generally added to a fictitious number that they use to describe the length of their penis.

The guy that tried to pick me up last night said he had an 8 and 1/2 incher. The way he talked, I didn't believe, so I didn't give him a chance to show me.

Person 1: Hey, wanna play something?

Person 2: (1/2)

Person1: I'm very sorry to hear that my friend.

Person 2: (1/2)

Person1: I'm very sorry to hear that my friend.

The person before made a mistake in their proof.

1. x = y

2. xy = y^2

3. xy - x^2 = y^2 - x^2

4. x(y - x) = (y + x)(y - x)

So far so good.

4.5. x = (y + x)(y - x)/(y - x) is what they did to get to step 5, which says:

5. x = y + x

This is wrong though. since x = y, y -x = 0, and so you can't divide by y - x.

1. x = y

2. xy = y^2

3. xy - x^2 = y^2 - x^2

4. x(y - x) = (y + x)(y - x)

The equation of choice among math paradoxers and recreational mathematicians, who unspokenly derive much satisfaction in exposing students’ fallacious or illogical reasoning that leads to the contradictory result.

Be it due to division by zero or squaring (or square rooting) both sides of an equation, few students wouldn’t want to know why “1 = 2” is logically plausible.
