look up any word, like eiffel tower:
 
1.
The lead singer of a band that can be of any of the genres of jazz, rock and roll, metal, blues or any of the like. The term is usually not used in the hip hop or rap scene. He is the one who is the face of the group, and usually gets all the groupies or first pick of them.

"Man, the frontman of that group is so amazing, the way he does his thing up on stage gets everyone hyped."

"Robert Plant was such a great frontman."

2.
An older guy that an older woman uses as cover while she secretly dates a younger guy on the side. The older guy is simply a "front" whom the older woman uses in public to help hide the fact she is having sex with a guy that could be her grandson.
They might seem like a happy couple but I heard he's just a frontman. She's banging some 20 year old.

A frontman is someone who refuses time and again to have anal sex with his girl. Because it's just nasty. Sure, the position's great, but what do we, men, actually get in return? It's just not natural...
Kevin, why won't you have anal sex with me? You're such a frontman.

A: Have you seen Rob theother day? I heard he's a real frontman!
B: Yeah! He's awesome!
