"Fish bowl" : TCAS display,
"Keep the blue side up", good advice, unless you are flying airbatic.
" Freight dog", you'll find them at Atlanta Harstfield, at around 4 AM near a 20 series Lear or an MU-2 carrying a bunch of checks.
" Vampire flight " organ transplant flight, usually in the middle of the night. This one I credit myself for.

"The
coffin corner or Q-Corner is the altitude at or near which an aircraft's
stall speed is equal to the
critical Mach number, at a given gross
weight and
G loading. At this altitude the aircraft becomes nearly impossible to keep in stable flight. Since the stall speed is the minimum speed required to maintain level flight, any reduction in speed will cause the airplane to stall and lose altitude. Since the critical Mach number is maximum speed at which air can travel over the wings without losing lift to flow separation and shock waves, any increase in speed will cause the airplane to lose lift, or to pitch heavily nose-down, and lose altitude. The "corner" refers to the triangular shape at the top of a
flight envelope chart where the stall speed and critical Mach number lines come together. Some aircraft, such as the
Lockheed U-2, routinely operate in the "coffin corner", which demands great skill from their pilots.
