The Vietnamese word "lẩn quất" is a verb that means "to lurk about" or "to hide and move around quietly." It often implies moving stealthily or being in a place without being easily seen, usually with a sense of avoiding detection.
In a sentence: "Cô ấy lẩn quất trong công viên suốt buổi chiều."
(She lurked around the park all afternoon.)
In a context: If someone is trying to avoid meeting a friend in a crowded place, you might say, "Anh ấy đang lẩn quất trong đám đông."
(He is lurking about in the crowd.)
