ouvre means to be? or to have? I think it’s a french verb or something? I am NOT a Harry according to any of the above definitions but took 3 years of French in High School so I will use my relative anonymity to protect my embarressment for being totally clueless about this.
BTW, I always thought a “Harry” is someone who is a little bit clueless or “chapless” about social norms in the yeshivish world (can be a ffb), usually Really ameRican. (Stress the r’s).
