5 o'clock shadow 

When you purposely walk in on your brother jerking off while your jerking off.

"I had that Paris Hilton video going in my room while I was cranking one out, when my older brother bill-dog walked in on me while he was beating off and laughing like a maniac! Bill-dog hit me with the worst 5 o'clock shadow! I was so embarrassed!"
