Like the sock your older brother put on his wank when he wopped off. 
deputy dawg, a little advice. Don't go telling anyone that you know what you're big brother's sock smells like. Even if you were little and just playing cops & robbers with it. And trying to be a scary robber with it, you pulled it over your head and the gooey stuff got stuck in your hair. And you cried a little when mom slapped and kicked your big brother out of the house for being a pervert.
NO DON'T TELL ANYONE!!!
Truth is that two of my sisters wondered what "smelled" in the room I shared with my brother, so they came in and cleaned it up. After they had done a ton of work, they ran across my brother's sock, and by the stains on it, deduced what it was and told my parents. Don't know what the folks told my big bro, but man, the room never "smelled" again.
