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???

lead bubble

Something (such as a character or vehicle in a video game) that can take a certain amount of damage without any degradation of performance, until the point at which it runs out of hitpoints and suffers spontaneous existence failure.

The idea is that it's like a bubble in the sense that when it's destroyed, it just suddenly "pops" out of existence, but it's made of lead, so it's stronger than an actual bubble.

The name comes from Megaman 2, where one of the weapons Megaman could get was called the "Bubble Lead". Which was probably a reference to how it "leads" you and finds hidden pits, but a lot of people started pronouncing it like the metal lead...

I put so many shield generators on my ship that it's practically a lead bubble now. 1,000 HP worth of shields, and 150 HP worth of internal components... one hit from a wave motion gun once the shields are down and it's toast!

Navy slang for a sailor stationed aboard a submarine. Opposite of a skimmer.

Bubbleheads consider skimmers to be targets that simply haven't been sunk yet.

Bubblehead Road 

A secluded street in unincorporated north St. Louis county, official name is Carrico Road.
Urban legend states something to the effect that years ago, people settled near the end of the road. Through years of inbreeding, the descendants of the original settlers developed hydrocephaly, or "Water on the Brain," which caused their heads to be oversized, hence the term "bubblehead."
This is a relatively famous urban legend in NoCo St. Louis, with many residents convinced of some truth behind it. Indeed, when you drive to the end of the road there and several "No Tresspassing" signs. I mean, A LOT of signs. I've heard of many people getting chased off at night by unseen figures in the woods.
Mainly, it was just fun to take chicks down there and tease them about the Bubbleheads.

Bubblehead Road is one of the creepiest places I've ever been.
