Bubble Lead
A terrible weapon from Mega Man 2 that travels along the ground.
Make no mistake, though it may be gray in color, it's actually "Lead," not "Lead." (Because the bubble "leads" in front of you.)
Some dipshits seem to think that it's slang for genitalia, but they are 100% making that shit up.
Bubble Lead is also super effective against aliens/holograms.

GAMER: ITS PRONOUNCED "LEAD" YOU ABSOLUTE FUCKING MORON???
