This is NOT your grandfather's cane -- unless your grandfather is super pervy or Axl Rose.

Rose has been hobbling around England this week using a walking stick, but little did we know what's under his hand is the most badass, rock 'n' roll senior citizen accessory ever.

The stick's sterling silver handle features a naked couple doing, um ... what naked couples do.

Axl's slowly recovering from his broken foot, but once he's fully healed -- he's gotta keep this thing handy. 

Limping's never been so pimpin'!
