Poke me?

What in the fuck is poke? I can understand grope, but poke? Is it sexual? It seems somehow sexually charged, but oddly teenage; somehow timid and uncomfortable. It is PC, but physical, but not physical because it is virtual, but not somehow gay between buddies, but often mildly erotic between sexes, or silly within families, but playful. Face it, it is motherfucking vague. The last time you actually poked someone (for real) you were a pimply faced awkward doofus that masturbated 8 times a day. Poke me? Wash the semen off first. I prefer direct communication. I am an adult, and very happy to have the horror and doubt of youth behind me.
