"Top off" a pilot who wont go anywhere without a full bag of gas, even if it is a 60 mile round trip inland VFR.
"Captain Crunch" a pilot who breaks stuff or is PIC on an aircraft when things get magically broken and he didn't see anything, hear anything or notice anything up to and including broken vent window sliders, missing fuel caps and mysteriously self inflating life vests. Has an annoying habit of grasping the interior plastic trim around the pilot's door door post and heaving his ample arse into the cockpit, crunching that nice brittle bell plastic to dust. Swears up and down it was like that when he did his pre flight. (HA!)
"Button boy" a pilot who will futz with every switch, knob, lever, setting, frequency, menu and widget in the aircraft because he is bored, obsessive compulsive or is just wired that way.
