when your brain crawls out of your head then this helps keep it inside your brain-case. but it must be left to dry for at least 4 hours or it will just escape again.

A song that you can't get out of your head.
Damn it! That "I'm a loser" song is brain glue -- it's been going though my head for two days.

When it feels as though bits of your brain have been disconnected, (ie when your feeling stupid), this substance helps to stick them back together again. Sadly, has not yet been invented :-(
I went out partying alll night, and was in serious need of some brain glue the next morning!
