I don’t know if this dude was just camera shy or what, but if you get caught by your girlfriend pantless and under the covers with another woman, you’ve got a lot more explaining to do than just saying “I didn’t do nothing” and “chill.” Unless she literally appeared out of thin air at the exact moment his girlfriend walked through the door, then that was the wrong time to have a “cat got your tongue” moment.
Who knows what happened after the camera stopped recording, but odds are there wasn’t a lot of “chilling” going on.
