Blurring bricks
Blurring bricks occurs when two people decide to perform anal sex, due to the other hole being closed for construction, and the receiver doesn't properly clean their anal cavity. The giver then smears the poop along their butt cheeks, hence "blurring their bricks."
Angela and Cole were getting hot and heavy but one of them wasn't mentally prepared to have vaginal intercourse yet so Cole ended up blurring bricks.
