Back in the day LPB was someone with low pings (remember dial up was 150 to 300ms sometimes) and they'd have an upper hand on games before they were "unlagged" with prediction code.
A common lament among the dead 15 years ago in real time online gaming...low ping bastard/bitch, basically just saying the only reason you got the kill is because your ping is 60ms and mine is 250ms.
