Small-browsing is a method of "stealthy" web browsing for when incognito mode just doesn't get you off. Small-browsers drag the corners of the open web page inwards, creating an air-tight, sealed window for the discreet viewing of pornographic or otherwise nsfw material, typically in a public setting. While the majority of small-browsers small-browse in classrooms, they have also been known to participate in small-browsing within libraries during lunch or their personal time. Please note that small-browsing should never occur in private, and should always be done without shame.
Tim: Hey, is that kid looking at porn?
Joe: Most likely. Would you look at the size of his window? He's totally small-browsing.
Tim: Golly, Joe! You sure are observant! Jeepers, no shame at all!
Joe: No shame, no pain. That's the motto.
