Y'all know who killed 'em filled 'em with the lugars from they Rugers
Or their Desert

from The Notorious B.I.G. (Ft. DMC) – My Downfall Lyrics on Rap Genius

Mom is yelling out how his friends know who filled them with bullets from Rugers or Desert Eagles.

Lugers refers to 9x19mm ammunition, commonly known as 9mm luger, 9mm parabellum, or 9mm NATO, chambered in such weapons as the GLOCK 19, the aforementioned Ruger P89, or the Jericho 9, commonly known as the Baby Eagle.

It’s not “or the Desi”, it’s “or they’re Desert” meaning the Desert Eagle pistol
