The ecstatic and thrilling feeling you feel when:
1) You see someone extremely hot.
2) Someone you love does something really sweet or good to you.

A person who needs to man up and grow a pair. Often the 'melt' will be approached by a member of the opposite sex, only to run away and cry as they do not know what to say. This results in them appearing to be either homosexual or simply clueless about life.

This is actually an old slang word for Vagina.
Used particularly in Ireland

Someone who bails out, and like an ice cube, 'melts'

An individual so attached to their boyfriend/girlfriend that they have seemingly melted in to form one person. Often the 'Melt' in question will refuse social invitations unless accompanied by their keeper

When you commit to an event or say you will do something, then don't do it and make up a shit excuse.

Can be used as a noun or verb.
