Liegraine 

A Liegraine is when you call in sick to work saying you have a Migraine when you fancy a day off. Its like a Migraine but is actually an elaborate work of fiction which enables you to take the day off.

A Liegraine is an excellent tactic when you have a job interview elsewhere or just fancy a day of sitting in your underpants playing video games or frenzied masturbation.

Nathan - "I can't come to work today because I have a migraine"
Manager - "Ok, we will see you tomorrow, hope you feel better soon"

Nathan - "Excellent now I can surround myself with high resolution games and multi window hardcore pornography."

Rich - "How was your day off man, you recovered from the Liegraine yet?"

Liegraine 

A migraine that is also a lie. Use of lying about having a migraine to get out of things you don't want to do.

"I'm calling in sick with a liegraine, I can't be bothered today." "I feel a liegraine coming on."

Lifegraine 

It’s literally life causing you to have a migraine
The constant thought of you having to be alive is just so much that you get a migraine.

Nicer way of saying depression maybe?

“Ugh, great can’t get out of bed because I got a lifegraine”
