Prior to “Big Mouth” Season 4, Lola was just another Nick Kroll to me. The crass class bully is one of at least 18 characters (!!) voiced by the series co-creator, and the whiny vocal fry he channels while playing this atypical mean girl does little to mask his typical “rich dick” schtick. Nor should it. Lola’s abrasive behavior is all the more intimidating (and hilarious) thanks to the furious baritone powering her point of view. Kroll is at one with Lola, just as he is with Maurice (the Hormone Monster) or Nick (who’s based on Kroll as a young boy).
