Making a Sandwich is code for jerking off,spanking the monkey,rubbing one out, etc. It is often used when someone asks you what you've been doing but would rather not express to the world that you were in fact playing with yourself. The expressing is usually followed by a quick wink and maybe a nod.
"Hey Jason, where the hell have you been? What were you doing?" ..."Just making a sandwich." 'wink'

Internet slang for any form of masturbation (including masturbation of another person or mutual masturbation) while typing. This term originates from the fact that both making or consuming a sammich while typing, and masturbating while typing often have very similar looking, and quite sloppy results.
