1. The main character on HIMYM. While Ted is sweet, awesome, and romantic, he can also be rather douchey (and that's douchey, not douché) as a reflection of his personality in college. His main goal during his late 20s and early 30s is to find a wife, and he pursues many ill-fated relationships to fulfill this goal.
2. A man whose life is way too focussed on getting married and having children.
3. A noted fictional porn star, sex architect, and philanderer described in tedmosbyisajerkcom
Man: Guys! Why am I not married yet? I'm almost 24! My biological clock is ticking! I'm so lonely in this world! I just want a wife and lots of babies to call my own!
Everybody else: Dude! Don't be such a Ted Mosby. Besides, you are a guy, you don't have a biological clock.
