Jogger Pants 

Basically a pair of pants with the bottoms made like elastic.There are two types of jogger pants
Jeans:These are like regular pants but with elastic bottoms.Mostly worn khaki style by African Anerican males

Sweatpant:These are like a sweatshirt for your legs.The bottoms of these are exactly made how the cuffs of your sweatshirt are made.These i prefer more because they have dope designs and patterns and they remind me of those pants teens used to wear back in the Early 90s such as Fresh Prince or Saved by the Bell

"Bro did u see those sick tribal print sweatpants at rue21"

"Nah,those arent sweatpants theyre joggers, but im really diggin those jogger pants that have 90s Nickelodeon cartoons on it

I said, you look fat in those pants! 

An effective rebuttal used by a man who has just been denied dancing privileges with the woman of his choice in a noisy club.

Man (yelling over the music): "DO YOU WANT TO DANCE?"
Woman (with a disgusted look on her face): "Not a chance!"

Man: "WHAT? NO. I SAID, YOU LOOK FAT IN THOSE PANTS!"
