Comment: My sense is that this is usually used in referring to someone who resembles someone else of quality or solid character, but it doesn’t have to. I avoided some similar “size” comparisons that could have negative connotationsn2, like “crumb” or “crust”, but using them could easily refer to someone of less character, on either side of the comparison.
