The nickname given to people, generally white boys, who are not hard enough to take part in hardcore activities that are likely to cause them physical or sexual pain, and therefore are like small boys and are weaker than grown men.

The name can be revoked and a new nickname, typically 'Manly', can be given, if the "boy" gathers the courage to take part in hardcore activity.
Boy1: You can't call me boy arms any more.
ManlyMan Why not?
Boy1: Because I got some sweet clunge action in Spain boii.
Manlyman: Oh yeah, nice one. Manly. You still couldn't bench 200 though.
Boy1: yeah....
