Your mileage may vary, but I find that the line of TMI is often clear to me after the speaker has already crossed it. In this case, I think I can safely state that, for me, the relative humidity of the herp diaspora's collective thong regions qualifies as TMI. Other examples of TMI that have recently been revealed to me include the fact that a co-worker sleeps with his pet cat between his legs in his thong region and the fact that a friend's ex-girlfriend is fond but very gastrically-intolerant of broccoli.
