What is Faceover?
1.
Similar to a hangover, in that it occurs after a night of drinking, although the symptoms are not a headache, etc. but rather that the individual facebook friends all the people they met the previous evening.
"Oh man, I had a huge faceover this morning, but couldn't add everyone i wanted to as friends because I couldnt remember their last names"
