Minoxidil - Chemical widely used for the treatment of hair loss. It has been proven clinically effective in both the prevention of loss and in establishing varying degrees of hair re-growth in males and females suffering pattern baldness. Minoxidil must be used indefinitely for continued support of existing hair follicles and the maintenance of any experienced hair regrowth.

May have significant side effects, including weak erections and decreased semen production.

Also, conveniently rhymes with cocaine, resulting in its frequent appearance in rap lyrics.

A particularly munt-filled beer drinking event. Competitors compete head to head in an event in which they must skol one beer at each of five stations, and sprint around 50m between stations (often a circuit is set up with the first and last stops at the same station). Notorious for shaking and bloating the stomach while drinking, causing mass amounts of high-velocity chunder into bins which are generally kept at the stations.

Ockham's Rogaine is a way of calling "foul" on a complex, fantastical claim about almost anything. It is the opposite of Ockham’s razor, William of Ockham's classic formula. Ockham’s razor says that among competing explanations, we should prefer the simplest one. A razor cuts away excess "hair" and simplifies loopy reasoning. Rogaine, figuratively, grows it and creates a long, unruly line of thinking.
That guy at the bus station must have poured on a lot of Ockham's Rogaine to get an alien abduction, Pope Francis and the Czech lottery, all in the same conspiracy.

Are you bald and tired of being referred to as Mr. Clean? Restore your confidence with a nice healthy dose of rectal rogaine, and no one will be calling you Mr. Clean anymore.
