If a girl tells a guy a bit too late that she doesn't want to receive his special juices, he may have no choice but to ejaculate on the nearest wall. Bonus points for hanging a poster using the sticky stuff on said wall.
College guy 1: Great Pulp Fiction poster man!
College Guy 2: Thanks. Your Mom and I were wallpapering last night. She was so good we also stuck my Animal House poster to the other wall.
