There is a misconception in your inquiry; "wast top of heap" is not a recognized phrase or idiom in the English language. It seems to be a combination of words that do not commonly collocate. However, I can provide you a definition for each word separately.
1. Wast: "Wast" is an old-fashioned past tense form of the verb "be" used in the second person singular. It is derived from early forms of English, such as Old English and Middle English, and is an archaic way of saying "were." Therefore, "wast" can be understood as the old-fashioned way of saying "you were."
2. Top: The noun "top" refers to the highest or uppermost part of something. It can be used to describe the highest point, the upper surface, or the apex of an object or structure. Symbolically, "top" can also refer to the summit, the best or most important part, or the position or status of being the best.
3. Heap: "Heap" is a noun that denotes a pile or gathering of things, which are often arranged in a disorganized or untidy manner. It can be used to describe a large quantity or number of objects or an untidy accumulation of various items or materials.
In sum, the phrase "wast top of heap" appears to be a combination of archaic and modern language. However, as a phrase, it doesn't have a distinct or commonly understood meaning in English.
