Ginger Hello

A form of greeting used by a red-headed fuck where s/he, upon arrival, either gives you a jolly "hello" and/or exposes his or her genitals to you. These are the ONLY two options.

Either option is definitely perceived as offputting and unenjoyable.

Gary: Ugh... P Dawg gave me the old ginger hello when he showed up at the party last night.
