O.E. prica (n.) "point, puncture, particle;" prician (v.) "to prick," from W.Gmc. *prikojanan (cf. Low Ger. pricken, Du. prikken "to prick"); Dan. prikke "to mark with dots," Swed. pricka "to point, prick, mark with dots" are probably from Low German. Meaning "pointed weapon, dagger" is first attested 1552. Earliest recorded use for "penis" is 1592. My prick was used 16c.-17c. as a term of endearment by "immodest maids" for their boyfriends. As a term of abuse, it is attested from 1929. To prick up one's ears is 1587, originally of animals with pointed ears (prycke-eared, of foxes, is from 1523). To kick against the pricks (Acts ix.5, first in a translation of 1382) is probably from sense of "a goad for oxen" (c.1350).
