All thin girls are not petite but, all petite girls aren't necessarily thin either.
(Sometimes men can be referred to as petite when they are the male equivalent of the definition above.)
Example 2: Ashley is 5'6, wears size eight shoes, and weighs one-hundred pounds. She's definitely very thin but, still not petite.
Example 3: My mother weighs over one-hundred-fifty pounds but, is only 4'11 and a half. She is obese but, she still shops in the petite clothing stores because of her short stature and size five feet.
2. A general term for those pansy wuss wuss folk
3. A descriptor for a person who fails miserably at a task.
(to be screamed in said person's general direction)
