Top Definition
A condition under which the sufferer's brain physically aches. The brain shuts down normal functions and refuses to work with you to achieve anything.

Leads to confusion, inertia, drowsiness, blank staring, unresponsiveness, nonsensical gibberings, numbness of the senses, difficulty in forming or grasping simple thoughts and concepts and immobilisation of the body.

Commonly a result of overindulgence in intoxicants of various forms, lack of sleep and/or workaholism.
E.g

Person one: Heya, how're you today?

Sufferer: uhhhhh

Person one: Whats up? Are you ok?

Sufferer: uhhh errrr brainache... meh
