A joke often used in the
YouTube comments section, in which someone says "I switched to porn when my mom walked in, it's easier to explain."

original way, when in reality it's been
plastered all over YouTube thousands of times. Someone who says this is often referred to as a faggot.
Person A: "Lol, this video is so weird I switched to porn when my mom
walked in, it's easier to explain!"
Person B: "This joke has been viewed thousands of times and as such has been rendered completely humorless. I imagine even the dumbass that came up with
the joke is weeping
right now."
