One of the older memes of 4chan, how do i shot web actually comes from the Something Awful Forums, more specifically on a goon-only Natural Selection server. The server was frequented by FYAD posters and the catchphrase moved to FYAD before spreading across the forums. Naturally, once the /b/-tards (many of them banned goons) picked this one up, it, like most of the rather interesting memes they have, circle jerked itself to staleness. In Soviet Russia, web shot you.
“Shot web” may be replaced by any past tense verb + noun combination, such as “How do I ate myself to death?”
The proper answer is ¯\(°_o)/¯
