"honey why are we still hanging around this immature fuck?"

"cause he´s a nice guy and somewhat funny - don´t be so hard on him and slip your fingers into my panties"

Fucktonne 

Theoretical limit of weight based on the maximum amount of mass that could be considered to still be within the bounds of earths normal gravity.

Impossible to achieve as adding that much mass would alter the Earths properties to the point of altering the gravity on Earth.

Covering the entire Earth's surface with 62 miles of super dense substance (62 miles at sea level, adjust accordingly)

The weight of said substance would be considered a Fucktonne

fucktion 

Erotica, erotic fiction.

Related to fanfucktion.

They're claiming that her new book goes under the Romance genre, but it's really just plain, simple Fucktion. There's no emotional connection between the protagonist and her partner.
