When your black ballsack gets so sweaty and drenched in cum that it resembles a hairy malteaser. Often seen in the hands of Liz or Samantha on a Tuesday evening.
Last nightthe party got so wild that we ended up in his room, by the end of it his ball bag looked like a Hairy Malteaser
a girl ( or boy ) who is a brunette/dark haired person who does stupid things, or has "blonde moments"
eg, a brunette walks into a glass door! everyone calls the brunette a malteaser as she had a "blonde moment" cuz the brunette is dark outside but blonde inside just like a malteaser
