Introitus 

The outside hole before you enter the vagina. You throw this word around to make yourself look smart in front of your friends.

While playing "just the tip" with my girlfriend I just barely passed through the introitus

Parous Introitus 

A hymen thats been blown away by a gigantic cock, often resulting in the unification of the two primary orifi (plural: orifice) into a vaganus.

1) The hunt for Red October led Sean Connery's team into the depths of Katherine Kuhlmans unchatered poes. After the submarine passed through her heavenly gates she was left with a terribly messy parous introitus, later spiritually healed.

2) I have SUCH a huge parous introitus, I can fuck a donkey sideways.

Introclusion 

The rare event or phenomenon of including introverts into the social sphere on a massive scale. Introverts that are part of the event will find social interaction with large groups to be more natural and less likely to bring on anxiety.

Dude, Pokemon Go is causing introclusion like no other time in history. I've never seen so many introverts out and about interacting with others so easily.
