tick 2 (tĭk)
Any of numerous small bloodsucking parasitic arachnids of the families Ixodidae and Argasidae, many of which transmit febrile diseases, such as Rocky Mountain spotted fever and Lyme disease.
Any of various usually wingless, louselike insects of the family Hippobosciddae that are parasitic on sheep, goats, and other animals.
Any of numerous small, parasitic arachnids of the suborder Ixodida that feed on the blood of animals. Like their close relatives the mites and unlike spiders, ticks have no division between cephalothorax and abdomen. Ticks differ from mites by being generally larger and having a sensory pit at the end of their first pair of legs. Many ticks transmit febrile diseases, such as Rocky Mountain spotted fever and Lyme disease.

1. A jiffy (sense 1). 2. In simulations, the discrete unit of time that passes between iterations of the simulation mechanism. In AI applications, this amount of time is often left unspecified, since the only constraint of interest is the ordering of events. This sort of AI simulation is often pejoratively referred to as "tick-tick-tick" simulation, especially when the issue of simultaneity of events with long, independent chains of causes is handwaved. 3. In the FORTH language, a single quote character.
