look up any word, like donkey punch:
When someone (usually with long legs and large feet) invades your under-the-table space with their legs and feet making accidental contact with yours. Often results in an awkward apology.

This originated when neighboring co-workers' under-the-table space were often violated by Rylan's extended limbs.
"I've been riolated!"
"Please stop riolating my space, thank you."
