What's this?

excluding(*elements) public

Returns a copy of the Array excluding the specified elements.

["David", "Rafael", "Aaron", "Todd"].excluding("Aaron", "Todd") # => ["David", "Rafael"]
[ [ 0, 1 ], [ 1, 0 ] ].excluding([ [ 1, 0 ] ]) # => [ [ 0, 1 ] ]

Note: This is an optimization of Enumerable#excluding that uses Array#- instead of Array#reject for performance reasons.
