Kiss

More of a "tongue-transferral process."

A kiss is a peculiar sort of human bonding ritual involving (sometimes mutual) oral contact. When properly administered by the correct agent, it can provide an incredibly potent power boost to Transformers, with occasionally unpredictable results.

Transformers in general have a problem understanding the phenomenon. For example, while Highbrow saw Gort kissing his incredibly hot girlfriend on Nebulos, he assumed it was some kind of data transfer.
