I name them like any other method. If you look at the Standard
Library classes, they do so too. Like Object, for example:

002:0> Object.new.private_methods
    => ["exit!", "chomp!", "initialize", "irb_eval", "fail", "print",
"binding", "irb_binding", "split", "Array", "gem", "format", "chop",
"iterator?", "catch", "readlines", "trap", "remove_instance_variable",
"gem_original_require", "getc", "returning", "singleton_method_added",
"caller", "putc", "autoload?", "proc", "pp", "chomp", "block_given?",
"throw", "p", "sub!", "loop", "syscall", "trace_var", "exec", "Integer",
"callcc", "puts", "initialize_copy", "load", "x",
"singleton_method_removed", "exit", "srand", "lambda", "y", "DelegateClass",
"get_line", "global_variables", "gsub!", "untrace_var", "print_line",
"open", "`", "method_missing", "system", "Float", "require", "gets",
"abort", "sub", "singleton_method_undefined", "get_lines", "test", "rand",
"eval", "warn", "local_variables", "chop!", "fork", "set_trace_func",
"printf", "raise", "scan", "Rational", "String", "sleep", "select", "gsub",
"sprintf", "autoload", "readline", "at_exit", "__method__"]

Except for some rare cases where __something__ is used, but those are ruby
core methods and
you shouldn't use that pattern.

yep.

I count better readability as a good reason.

I like 4 better

I agree.

You sometimes do, if you want to be DRY.

All those styling conventions are 100% subjective. [removed styling advice]

Although you didn't ask for styling guide, here we are again... :-)
It's too damn easy to slip into that topic... I had already written 3
paragraphs.
