When a guy's cock is semi-hard but won't stay up, like a twizzler. A twizzler is hard and biting into it, they are very chewy; however, they won't stay straight up when held out, they slowly fall over.
Girl 1: Did you and Jared finally hook up?
Girl 2: Yeah but he could only get a semi. He had twizzler syndrome.
