Is it posible to make a verb to let the player make a copy of himself ?

Yes, you can. If you want it to be an exact copy, you can just create a new object with the same type path as the player, and copy all of the important variables (skipping a couple of internal ones such as 'client' or 'key'). To do this, you have to loop through the 'vars' list all objects have.

var/list/skip_vars = list("type","vars","key","ckey","client")
// list of variables to skip when cloning

mob/verb
  clone_self()
    var/mob/M = new src.type (src.loc)
    // create a new object with the same type as the player

    for(var/i in M.vars) // loop through all of the variables the clone has
      if(i in skip_vars) continue // skip all of the unnecessary and internal variables that should not be copied over
      M.vars[i] = src.vars[i] // otherwise, copy the same values of the variables

You'r code dosent work when i run it its unable to determine the atom type.

In response to Miran94
No, his code is fine, but he missed some vars in the 'skip' list - you will get some "can't write to var" errors, etc.
Anyway, before making topics, search first. There are probably tons of topics about this. [link]

Examples to go with that proc: 
mob/verb
    create_clone1()
        /*this approach doesn't specify a datum to copy over to,
        therefore the proc creates a new one of the same type
as the cloned datum, in this case a /mob*/
        src.Copy()
        src << "You create a clone!"
    create_clone1_x()
        //this just demonstrates the usefulness of the proc returning\
        the object reference
        var/mob/clone = src.Copy()
        clone.name = "[src]'s clone"
        clone.loc = get_step(src,src.dir)
    create_clone_2()
        //this approach instructs the proc to copy over to a \
        'custom' (existing) datum.
        var/mob/clone = new()
        src.Copy(clone)
        clone.name = "[src]'s clone"
        clone.loc = get_step(src,src.dir)
