Yo Mama Extreme Voice Edition
Everyone loves a good "your mama" joke, with the possible exception of, well, your mama. It's all in good fun, though, and that's certainly true of this app. It may surprise you to learn that there are several your mama apps vying for your attention and, in some cases, your 99 cents in the App Store. Yo Mama Exteme Voice Edition sets itself apart by offering pre-recorded spoken renditions of more than 300 your mama jokes. There's also a free version to try before you buy.
The app includes an Internet mode that enables users to rank jokes, suggest new ones and send favorites to their friends via e-mail. New jokes are added to the site on a daily basis, so you need never fear not having a fresh yo mama joke at your fingertips.
As mentioned, there are a lot of apps to choose from in this genre (the App Store lists 17 your mama applications), so you'll want to spend some quality time selecting the best one to meet your insult requirements.
