- verb, (-sated, sating)

To pre-heat an object or region of space for oneself or others to experience. Thermonsation, the process by which one thermonsates, is commonly referenced in public spaces whereby a stranger has pre-heated an object of interest preceding an individual's arrival.

Derived from a conjunction of the prefix "thermo", from Greek meaning heat, and inseminate, meaning to sow or implant seed into.
