Platouch is defined as the act of touching friend in a platonically loving way. It can be a hug, pat, even full on cuddle but the intention is not meant in any intimate way. Not all people are in favor of giving or receiving frouch but those that do now have a simple explanation for the assumption that a hug or cuddle is more than it is.
Person 1: I saw you and him cuddling. Are you guys dating?
Person 2: Nah man, there was just a little bit of frouch happening.
