according to Katt Williams, a fuck number is the number of times it takes to hump a girl before a guy cums. Can be determined by jacking off and counting. For a girl, it is determined by the number of times she gets pounded before she has an orgasm.

The financial number at which you can opt not to work.It's different for everyone...but generally speaking...if you buy into the "American Way of Life"...that number is somewhere around 5million liquid.At that point-you have a barrier against "the unforseen"(illness/injury)...or the fully known. (divorce/criminal children)Hefty appettite for booze,sex,and gambling?Triple that number.
Between his ex-wives,children,and jet set travel-James the attorney has a higher FUCK YOU NUMBER than Joe the plumbing contractor.

He: Honey, what hole are you looking to have filled?

She: I’m so horny … try ‘em all. Let's fuck by the numbers.

He: OK, I think I will go around the horn. I’ll start with numero uno (mouth), proceed to #2 (pussy), then finish in #3 (ass).

<Fuck cycle can be a continuous loop, or can be mixed up a little … going, for example … 3,2,1 or 3,1,2 or 2,3,1, or 2,1,3 or 1,3,2. The introduction of both nostrils … holes 4 and 5, can be added to spice things up a bit.>

Get the fuck by the numbers mug.
An annoying occurence when you text a number one time, and T9 uses that as your default in the future.
Last night I texted Stacy to come get in my bed, but since I have texted the number 46 before, T9 sent it as "Come get 46 my bed." Stacy was so pissed. I was totally T9 number fucked.
