greyout 

Temporary lapse of memory/mental fogginess/amnesia often due to excessive alcohol use. Not to be confused with blackout, as a greyout occurs for short intervals between one and five minutes.

Al: So you drunk texted me 30 times yesterday
Amber: What!? I don't remember that...
Al: So basically you blacked out?
Amber: Nah, I remember everything except for like 5 minutes of last night.
Al: I guess you must have had a greyout!
Amber: Sweet!

greyout 

A alcohol induced midday state simliar to the blackout only due to it occurring midday, the sunlight turns the black to grey.

Sally is such a trainwreck, she spends her Sunday mornings at brunch getting greyout in order to make her drunken behavior acceptable.

Grayout Drunk 

Not quite as drunk as being Blackout Drunk. You're still capable of making some form of conscious decisions, but whether or not they're wise is to be determined per individual situation. You also remember about 56% of what occurred while under the spell of the mistress "Rum Punch." Regardless, you still walk around like a moron and tend to exist haphazardly.

Kyle showed up for work grayout drunk yesterday. He was on time, and punched in, but then just disappeared for 45 minutes and we found him having a full on heated argument with a storm drain and a mop bucket.
