Dirty Veronica
When a female wipes her finger into her own vagina after a long hot day and then wipes her finger on an unsuspecting acquaintance. Preferably the unsuspecting acquaintance would have facial hair so a cum ball may be left behind on the mustache.
My husband had not shaved for a few days so it was a good time to give him a dirty Veronica at the July 4th party in LBI. He was unknowingly talking to Jeff with a cum ball in the corner of his ‘stache.
