Your mom is the first defense is sixth grade boy humor, it’s constantly overused and makes you question the sanity of society as a whole. Your mom is also commonly used by lesbians with no humor and are trying to be funny, yeah I’m talking to you.
Example 1
6th grade boy 1: guess who I did last night
6th grade boy 2: who?
6th grade boy 1: YOUR MOM!!! OOOOOOH
Random kid passing by: wtf?!
Example 2
Random person: hey wanna hang tonight
Lesbian with no humor: sorry can’t tonight I’m busy doing…
Random person: busy doing what?
Lesbian with no humor: YOUR MOM!! OOOOOH!!!
Random kid passing by: How do I keep hearing these conversations?!

Get the your mommug. 1. A very nice lady that makes meals for you and your family. Acts like she enjoys your friends company more than your's.
2. The response a middle schooler would give you, goes well with "who asked","Joe who?", and "To your left".
