Hoofbeats 

A term that encompasses all possible vocabulary, and whos definition is varying, instead, whos meaning varies based on the context it is used it, and also the users tone.

Evan: Last night I jerked off so hard i tore a layer of skin off my twanger.

Devin: HOOFBEATS! (High pitched, in this form, meaning Ouch)

Original context: Joe Dirt "You want me to put my head to the ground and listen for HOOfbeats?"

Similar to the Southpark episode in which the alien races' language was composed of only one word "Marklar" and whos meaning was determined based on context.
