Píča
Píča, sometimes short piča or pyča, is a Czech and Slovak profanity that refers to the vagina similar to the English word cunt. It is often represented as a symbol of a spearhead, a rhombus standing on one of its sharper points with a vertical line in the middle, representing a vulva.
The meaning is clear for most Czechs, Slovaks and Hungarians. In some other languages it has other spellings, but has similar pronunciation and carries the same meaning and profanity. Drawing this symbol is considered a taboo, or at least unaccepted by mainstream society.This symbol has occurred in a few Czech movies, including Bylo nás pět. In the 1969 drama The Blunder, Milan Kundera describes the havoc, both public and private, that ensues after the headmaster of a school draws the symbol on a blackboard.
Jaromír Nohavica confessed, in the 1983-song Halelujá, to "drawing short lines and rhombuses on a plaster".
