The definition of earplugs is when you are facefucking a girl and shge sucks at givven head, so you pull your dick out of her mouth and then procide to jizzz in each ear, so she cant hear and then you can call your buddy up and say how shitty the head was, and to not try for it
last night i was gettin head from megan and she was so bad i had to give her some new pearly earplugs
(pl.) Probably one of the best college accessories you can buy. Once they're in your ears, you're able to focus on your homework/exam/whatever without being distracted by outside noise, be it coughing, sniffling or small talk. Seriously, at least try taking an exam with them in. You can thumbs-up the definition later.
You don't need a study drug. You just need earplugs.
