SBD
ShaunaBaDheka... ranked #1 fool on every planet except Uranus... SBD has the 2nd highest voice in Berkeley (following "GOT A QWATA?" man), averages 4 hours of sleep per night, has the memory of a goldfish, thinks it's still the 90s, eats ramen noodles excessively, and is really good at face-planting.
"That weirdo is eating a bag of Fritos for breakfast and wearing a plaid jacket over a dress and is six feet tall and watching The Fifth Element... is this 1996 or is that an SBD?"

A sea-borne dive bomber of World War II, the Douglas SBD Dauntless. The SBD was the Navy's main dive bomber in the first two years of the war. SBDs sank all four Japanese at the Battle of Midway in 1942. Pilots often called their plains "Slow but Deadly."

A silent but deadly fart. A foul-smelling tile peeler eased into play without a peep. This is the favorite fart of the prim and proper lady, and is useful at lady's clubs, in elevators, in streetcars, and in church.
Swede Vejtasa was an SBD Dauntless pilot in World War II. He shot down seven planes in one day in 1942.

Melissa let an SBD right next to the punch bowl at the church bazaar.
