An amphibian is someone who switches up when you're not around, such as being fake, unloyal, untrustworthy or a snitch, much like then term snake but an amphibian is way worse then just that, to earn an Ampbihian title is a death sentence in the mean streets of NorthEast Philadelphia where the term originates, further more a amphibian can be marked either verbally within a group or by sending and/or commenting different reptile/Ambphian emojis on their social media
