When a person's facial expression and/or inadvertent phrasing or tone, give you a unwanted preview of what they might be like in the bedroom. Similar to the "o-face" from office space.
Ex. 1 "Although the singer struggled to hit the song's high notes, he succeeded in giving everyone a Bedroom peek"

Ex. 2 I know she was just asking for her pen back but the way she said "Give it to me" was a total bedroom peek.

Ex. 3 Any moaning, outside of a life threatening injury, is a bedroom peek.
