Throwing Shade is a weekly comedy podcast based on discussions of women's rights, gay rights, and pop culture, hosted by Erin Gibson (a.k.a. Feminasty) and Bryan Safi (a.k.a. Homosensual).

In both cases, the recommendations offer the rule of thumb to âstart with a shade that is too dark to see the weld zone.
