^ In the hierarchy of icky comments I'm not sure that one's especially icky. It's certainly icky but - from distant memory - pubes came fairly late in adolescence. I don't think I'd've appreciated any 'games' being played with me at the time all the same.
Given foetuses can/do pee ('n' poo for that matter) in the womb that latter one really is a bit of a statement of intent
I know I've heard the bleed/breed one plenty times when I've worked at various places where it tends to be very male-dominated. This would be before the Paedogeddon!!! hysteria really got in to full swing though and can't believe anybody would be saying it even in jest now cos it just reeks of the Saviles. Always found it interesting that those very same blokey-bloke chaps would quite happily go from bleeding/breeding remarks about whoever the borderline legal singer/actress/sleb of some description was at the time and with the next breath go off on some vigilante rant about nonces. And it often did seem the two topics would come along in fairly close succession which always made me wonder if there was some flickering awareness of understanding of what they'd just been sniggering and drooling over a moment before. Dim awareness admittedly but some level of awareness at least.
