Tab-Hoarder 

The Tab-Hoarder is one who is reluctant to close internet tabs, usually resulting in a buildup of chaotic tab clutter on the browser toolbar.

Sometimes results in "Browser - Paralysis".

Usually consists of multiple YouTube windows, a few StumbleUpon tabs, Facebook, Break.com, I-players or random episodes of pirated TV shows etc...

The Tab-Hoarder will always choose to open (yet another) "new tab" instead of overwriting current browse window. It may come in use later.

- "No wait - don't close that window - I might come back to it later."

• reserve useless tabs in the mind for future use : as adj. ( hoarded)
