All Dayer 

Staying awake all day to try and reset your body clock.

Normally follows after a sequence of going to sleep at increasingly later times, until your going to sleep around dinner. The only cure is to hack it through the day and go to sleep at a sensible time.

Need to go to sleep at a sensible time, gonna do an all dayer.

All-Dayer 

The feeling one gets after pulling an all-nighter. You start to feel so tired that you aren't even tired anymore. You eventually start to feel like you are in a dream. Sometimes when under the influence of an all-dayer people might start talking to complete strangers and be completely unaware of what is going on around them. You might also feel a strange sense of happiness and confidence.

All-dayers can be fun and scary at the same time.

A marathon drinking session which starts around lunch-time and carries on until dawn. Typically involves barbecues and beer gardens in Summer and warm pubs and Christmas jumpers in winter.

all dayer 

instead of an all nighter, where as most people fall asleep as soon as morning comes around, an all dayer extends it another 24 hours. This makes it a 48 hour awake period.

Nah man I'm not going to sleep; I gotta pull an all dayer.

all-dayer 

After an all-nighter, you have a new challenge: an all-dayer. It's when you stay up all day after staying up all night. Harder than it sounds.

"Hey man, I'm so FUCKING tired. Just pulled an

all-dayer."

"Woah, seriously!? That deserves something."

"I would like that "something" to come in the form of either a bed or a caffeinated beverage."
