Someone who is constantly singing during class.

If you have a brother or sister who is a singaholic, they also constantly sing around the house.

Most of the time their singing is actually very terrible and makes you want to cut your ears off with a knife.
Tim: Kira won't stop singing!
Harry: She's a singaholic, she sings all the time. even in the shower.
