A joining of the phrase Entertainment and Leach. Can be used as a noun or verb.

An eleach is someone who sucks off someone else's form of entertainment without an invitation- such as someone sitting next to you on an airplane watching a movie off your laptop screen or someone across from you reading an article on the back of the newspaper you're holding in your hand.

Eleach can also be used as a verb when describing someone's behavior
The guy sitting next to me was an eleach, if it had been a hot chick I would have at least turned on closed-captioning.

I was eleaching the whole flight because the battery died on my iPod and I didn't bring anything to read.
