Conflation of the expressions drive me up a wall and driving me nuts. Basically when someone is annoying you so intensely it's almost like they're kicking you in the balls. Hence the reference to the word "nuts."
Co-worker: How's the project with Amy coming along?
Me: Holy moly ... she's really driving me up my nuts. I can't stand her constantly changing her mind about everything.

After a guy blows his load; either solo or in the company of a tight pussy, and then blows another in succession.

The nut is only considered a follow-up nut, if two key pieces of criteria are met:

1.) The nut must be blown in the same session as the previous.

2.) The refractory period must not exceed 10 minutes in length, before the successive nut is ejaculated: “t > 10 = FUN”.

Should all criteria not be met (i.e. the refractory period exceeds 10 minutes in length; or the successive nut is blown in a future session, the nut is not to be considered a follow-up nut but instead falls into the classification of “The law of iterative nut busting”).
Dude, last night I blew a fat load in my wifes pussy and the pussy was so good that she squeezed out a follow-up nut which completely drained my sack!

After last night, I have been shooting blanks.
