What does "It's all you tab" mean?

I've just read a conversation on Facebook:

Boy: You should be a model!

Girl: It's all you tab!

What does she mean in the above context?

Update: I think i found the right answer, thanks @Janus Bahs Jacquet

That's all you talk/think about

Solution 1:

My guess is that it is a reference to the:

tabby cat

which has an etymology linking it to clothes (Wikipedia):

The English term tabby originates from the translation of the French phrase "striped silk taffeta", the root of which is tabis, meaning "a rich watered silk." This can be further traced to the Middle French atabis (14th century), which stemmed from the Arabic term attabiya. This word is a reference to the neighborhood in Baghdad, Attabiy (named for Prince Attab of the Umayyad Caliphate), where such silk cloth was first made. Tabby is also comparable to the Spanish word ataviar, which means "to decorate or to dress or wear" and often implies luxurious clothing.
