Expression used after the description and/or mention of an occurrence disgusting, foul, irrelevant, inconceivable, witty and/or random. Probably relates to an impossible or extremely gross pornographic scenario. Can be used occasionally with the family, but only if they're hella chill. Often quipped during an adolescent conversation about actual porn, but can range in topic choice. A poignant and lyrical way to respond to and outdo a remark. Can be translated into "n0w, 1h@1'5 b@d pr0n" if you so choose it, 1337 boi. Variations can render the phrase in the present, past, and future tenses. If delivered correctly, "now, that's bad porn" can send children, teen and adult alike into a spiraling path of laughter, but even a great delivery with comic brilliance can get you into a shitload of trouble. Take caution, and use wisely.
