Tan = fan

Bah-ee-kee = bike or motorcycle

Today he also kept saying "teem" which I think was in reference to "building" but I can't be sure, as he hasn't used it in other contexts.

Mah-oof = mouth - this is in reference to tongue actually, and I only made this connection when he referred to the "licky" emoticon as "mah-oof." He also calls the "evil" emoticon gato, I think because it has "ears."
