tabo + ulo = tabulo... hahaha I'm just kidding, but I have to admit that it was the first idea that came to my mind :P
Hmm, tabo (tab·o) = tab (key). Do tabulo signifas ulo kiu uzas tabojn. Kompreneble.
Aŭ, eble, ulo kiu trinkas multe da tro sukereman karbonatan akvon kiu nomas Tab™
More "finds itself", I think it was inspired by the meaning of the french "se trouver" (literally to find oneself, but means to be located). When I first learned esperanto years ago, I learned to use the verb loki, but it seems troviĝi has become the accepted way of saying this.
