So, the male, when encountering a female, bumps her on the bum to induce urination. He then drinks the urine. If he likes it, he’ll follow her around until she’s too tired to resist, and have his way with her. Ah, the romance.

I have a deja-vu from last new-year's eve

Female Cichlid fish carry their eggs around in their mouths. A male then tricks her into thinking she dropped some by having egg-like spots on his body. When she approaches and tries to suck them in, the male ejaculates all over her face, fertilizing her eggs whether she likes it or not.

This is my favorite
