Derivative of "barrel roll," most famously implemented in Star Fox 64 when Peppy exclaims "Do a barrel roll!," in what can only be described as a fairly recockulous fashion.
It is to add a "spinolo" like tinge to an action, thusly rendering it completely amoral and prude.
Also can be used as a noun, simply declaring someone a complete spinoloroll.
Jeez, Will! Your spinolorollocity is ruining this conversation! Stop using all that self-deprecating humor, you spinoloroll! Enough with the fucking spinolorolling!
-it is good to note that this term is often used with little or no prompting from third parties with little or no lives.
