conception 

an act of inception (planting an idea in ones mind) performed through an indirect mindfuck.

While dreaming if sounds from other people having sex (through a wall or in another room) infiltrate and start controlling your dream, an act of conception has been performed on you.

conception 

A violent process that happens when a daddy cell violently slams his head inside a mommy cell and the mommy cell consumes the daddy cell's head and leaves the rest of the daddy cell's body to rot.

Some believe that life begins at conception. I believe life ends there.

Conception 

A band that was formed in Norway, 1989 by guitarist Tore Østby, singer Dag Østby, drummer Werner Skogli and bassist Freddy Samsonstuen. In 1990, after a demo tape, Arve Heimdal replaced Werner Skogli and Ingar Amlien replaced Freddy Samsonstuen. A year later, Dag Østby quits, and the band is forced to search for a new vocalist. After many auditions, the band hooks up with Roy Khan, a classical trained opera singer.

Roy now sings in Kamelot.

conception 

the union of the sperm and the egg to produce a new life after copulation.

Amber and Tyrone had been trying so hard for a baby without success. Amber got the idea of having sex for twenty-eight days in a row with Tyrone. Bingo, there was finally conception, but Amber never found out exactly when her fertile days were. She was so big at graduation, her gown couldn't hide her condition. Tyrone's hard-on went unnoticed under his gown even though he was thinking of what he was going to do to Amber that night after they got their diplomas.

Prelude to Birthday. The Day after you came in a vagina.

Richard looked back on his daughters birthday and realized the panic he felt during conception was worth it after all.

Conception Balm 

Obviously semen but more specifically semen used as a lubricant after the performance of a creampie. In most cases, the person providing the semen will be the conception balm user at the time of second sexual encounter. If someone else is using your conception balm, it is simply sloppy seconds.

The second time is the best, especially when I leave behind some conception balm.
