In general, we can describe a quasi aromatic compound as a compound, which is ionic in nature with a counter ion, and the $pi$ electrons in such compounds follow Huckel's rule ($4n+2$). In other words, quasi aromatic compounds are those in which the charges present on the molecule are a part of aromaticity of the compound. Few example of such compounds are depicted in the diagram:
However, it has a deeper and broader meaning. For some complicated explanation, read given references.
