The lore is quite literally that this unit is tempting to guardsmen. They get more monstrous up the line, but Slannesh has to lure people in first and then twist it and push to excess. No young man started jacking off to dominant troons and chastity cages, they have to work up to it with increasing degeneracy.
They have a sort of charm effect that works as a debuff. They should make a typical hiveworld founding gaurdsman hesitate and wonder if he could suck on a titty and if the commissar would notice. At best he gets skewered while contemplating this, or shot by his commissar, at worst he gives into lust and becomes enthralled.
You see those butch crab lesbians and nobody started off with that shit. Chances are no matter how long you spent on /d/ you still never jacked it to that shit. That is some advanced weirdness. That's like rapy Tyranids. That would inspire every troop to fight to the death twice as hard and save a round for themselves.
The problem is Gamesworkshop hired feminists who insist that those are attractive women.
