Legally, yes. Would you want to? Since you came up with it, than yes.
You can register any name in the US, England, Canada or of like.
You don't have to register it as long as you use it in print and mutli-media. It must be used the same way (spelling and all) and not be contested.
Such as: The only issue you may have is if some other band already has the name or someone is currently using it. They may go after you legally to stop or want royalties for usage.
A quick internet search can help you.
There are actual band names like: Fartbarf, F*ckface (I added the star, but the band use the actual spelling), Exploding T*ts, Surgical Penis Klinik , Woodp*ssy, Maggot Sandwich, Tumor Circus , P*ss Factory, Rump Rangers...
the list goes horribly on......
