Definition

1. Verb:
   • To defecate; to go stool: The act of excreting feces from the body through the anus. This is a direct, informal, and somewhat vulgar term in Vietnamese.

Usage

• Important Note: The word "ỉa" is a blunt, informal, and crude term for defecation. It is generally considered impolite and vulgar. It is used in casual, familiar settings, among close friends, or to express strong emotion/contempt. It is not suitable for formal, polite, or public discourse. In medical or polite contexts, terms like "đi vệ sinh" (to go to the bathroom), "đại tiện" (to have a bowel movement), or "bài tiết" (to excrete) are preferred.
• The verb is used intransitively (without a direct object) to describe the action itself.
• It can be used transitively in specific, often vulgar, constructions (e.g., "ỉa ra" - to shit out).
