The genital equivalent of a soulmate. When you meet a member of the opposite sex and as soon as your genitals touch for the first time, the clouds break, a ray of light shines upon your crotches, choirs of angels start to sing and the world around you begins to crumble.

Oi mate is usually used to refer to a friend, comrade, or anyone basically. Its mostly used in England and Australia.

A sex position commonly seen in hentai and Rule 34 and sometimes porn. It is normally just the Missionary position (albeit exaggerated) from the view of the couple’s rear, with the added touch of the penetrator’s legs more up on the receiver’s legs for “deeper” penetration. It looks as though the penetrator is squating while in the position.

This position is commonly seen in breeding/impregnation kinks, with the receiver being skeptical of being pleased/fucked or just being cocky or superior, followed by a female egg being fertilized seconds within seconds of the penetrator cumming despite in reality taking several days or weeks of the woman to actually become fertilized. The receiver is usually crying out in pleasure as a result.

A similar position is the Pile Driver.

Basically "thanks, buddy".
