look up any word, like the eiffel tower:
 
1.
(Limited to) a long forum post or email message. Longer than 500 words. Not used to describe long product or entertainment reviews et cetera.

Coined from the word "visine" which is a brand of eye drops used for tired, sore eyes.

NB: Coined by a dude named 'dayveaux' (pronounced davo) in Oz. Guilty himself of this behavior. Changed spelling of the word as it is a trademark company product.
"dude, have you read this vysine? it may fix your problem".
"your vysine is completely off topic".
"if I see another vysine in this thread i'll vomit".
"check out this vysine, (url link) this dude obviously has nothing better to do".
