A man or woman who tells you too much about themselves on your first meeting such that it feels like they are ejaculating information all over you.
"Man that guy Rob wouldn't stop talking about himself last night at the party. He was really jizzy"

Friend 1: "How was your date last night?"

Friend 2: "Well he was trying to put the moves on me by telling EVERYTHING about himself. It was really jizzy"
