A fork of Rural Dictionary
Da cranky "shark week" period (pun not intended) of each month when a post-puberty chick feels da need to perform live music before an impromptu audience in da town square or city park.
Just like da "leave da hired help alone during intervals of intense household-chores activity" directives --- i.e., don't bother da maid when she's cleaning or da cook while she's baking, due to their being sternly laser-focused on said tasks, and thus any interruption might get you irritably whopped upside da head with either a broom or rolling-pin, respectively --- you should not "bother a lady while she's going through preminstrel syndrome", but should instead just let her play her instrument in peace!
