A person who compulsively collects and keeps many tabs open on their web browser. Also a person who refuses to close a tab on their web browser for fear that they will regret it in the future, and so ends up compiling more tabs day after day.
My one friend is such a tab rat; she's so obsessed with fanfiction that every time she finds a new link to a new fic, she will keep it open on her browser until the foreseeable future in case she needs to re-read it.
