Sheep Flu 

When someone thinks they have whatever random flu they hear about on WebMd that day.

Guy 1: OH MY GOD, I AM SO SICK. I HAVE THE SWINE FLU! ZOMG!
Guy 2: No, you just have a case of the Sheep Flu
Guy 3: Oh No! I heard you can DIE from that.

Sheen Flu 

Sheen Flu is when you're the victim of a massive and horrible hangover. It implies that you were partying like Charlie Sheen the night before, and may be on the brink of death.

Sean called off work today, yesterday's happy hour resulted in his coming down with Sheen flu.

Nice fluffy happy sheep

sleep flux 

The point in time when you'd usually be sleeping, but the computer moniter is keeping you awake. Usually you are really tired, but you are too lazy to turn off the computer; maybe you're myspacing, maybe you're gaming, or maybe you're just chatting. The boredom is so great, that you think the prospect of sleeping is too boring to try. You'd rather keep listening to music on iTunes late into the morning.

Guy A "Oh dude, i got like no sleep last night."

D-Bag Friend "Why dude, what the fuck is wrong with you, are you on crack or something?"

Guy A "No you sack of shit, I had intense sleep flux"
