meaning of the sentence 'Rover Wanderer Nomad Vagabond. Call me what you will.'

[Daemon99]

"Rover Wanderer Nomad Vagabond. Call me what you will"

Call me what you will

Can someone please tell me how is this line different from 'Call me whatever you like'?
Or do they both mean same? (is this line correct?)
