<p>It could also be the "Kaien" robot from Gintama, here is a picture of it firing from episode 235, and the dirty humor definitely fits the series, although I didn't hear that exact quote in the episode. </p>

<p>It's about a boy and a girl, and the only scene I remember is one in which they are in a fighting robot, facing off against a bad guy in a robot with a penis cannon. The robot fires a huge shot and an old lady says "quick! After it fires a huge load it needs time to recharge" and someone else says "sadly that's true about most men".</p>

<p>Another line in that same scene: the girl and boy are very cramped in the robot, the boy is rubbing up against the girls back, and she asks "what is that poking me?" He says something like "it's the growing tree of the puberty forest". I don't remember the exact line, it was years ago and it made me laugh.</p>

Well, the "penis cannon" meme comes from "Sora no Otoshimono" but pretty sure that's not what you're looking for.
