internetegrity 

Representing one's self online no differently that one would present one's self in person.

That guy's got internetegrity. When he LOLs online, people look at him funny IRL.

interneternity 

A period of time spanning from the second something is posted online, until the complete and total annihilation of the entire universe. Maybe longer.

Did you really post that pic of your ass boil? You might as well embrace celibacy.

Nah, it’s just for interneternity. I may still get laid a few thousand lives from now.
