We can tell "pimpier" is a form of pimp (pimpier → pimpy → pimp). I would say this usage is uncommon and/or unusual, and so it is difficult to give a precise definition. In this case, I would say the meaning is closer to impressive, skillful, remarkable, etc.
pimp
A pimp is someone who employs prostitutes — they work for the pimp, who gets a cut of their money. He pimps them.
Pimp is a word that has greatly shifted in meaning, as it sometimes means "great" or "cool," as in "That bike is pimp!" However, that's a slang meaning that many people, especially adults, won't understand or like. The main meaning of pimp as the boss of prostitutes is pretty creepy, because prostitution is illegal and pimps are not known for treating their workers very nicely. For some reason, pimps are known for their flashy dress.

As suggested above, pimp can be used to say something is cool, outstanding, impressive, excellent, remarkable. etc. As I mentioned before, "pimpier" (or "pimpy") is a bit unusual, but we can still rephrase it as something like
And yet you force us to do it... without shame or regret and the more remarkable shit you do is you convince us it's our idea...
I can't tell you why they translated it as worse. For the purpose of this joke, it is worse from the perspective of the comedian (or men). But I would have chosen a different translation.
It is not uncommon for comedians to use words in usual ways for comedic effect. This is true of colloquial speech as well.
