Tropes
- The Lad-ette: A common character type for her, most notably her roles as Dee and Mickey. Her character on Curb Your Enthusiasm had shades of this when she returned in Season 10.
- Romance on the Set: She and her Always Sunny co-star, Rob McElhenney, started dating in secret during Season 2 of the show before getting married in 2008. Similar to Charlie Day and Mary Elizabeth Ellis, this makes the vitriol between their characters even more amusing to watch.
- Slapstick Knows No Gender: A staple of her characters, who are often subjected to as much physical pain and humiliation as any of the men, if not more so.
