Is there another meaning for hp?

I've been watching some videos because I'd like to Plasti Dip emblems on my car. On the comment section, i noticed people asking how much "hp" is added and i'm not sure what they mean? I do know the joke of some Honda Civic drivers/ricers who think adding stickers to their car means more horse power. Could these people be reffering to a ricer joke or?

I think it's the same little side joke. Like adding flame decals on the side of the car adds 5 horse power, or if you're into sport bikes you choose the lime green Kawasaki over the black one cause it "adds 5hp".

Same joke.

Hi so try HP horsepower was 746 watts of electricity or 100 cc. The modern car is rated not in any of these but BRAKE HORSE POWER measured on a machine called a
Dynamiter this does show that over time and engine wear the BHP decreases with time and mileage. The fact seems to go over the heads of most young men especially americans who have such problems accepting that power is reduced to 50 % after 100k miles.
