A bastardized misspelling of the English word "please", usually spoken by Polish
people on the internet, particularily in games such as Enemy Territory and World of Warcraft. Sadly this is just
one of many English words the Polish
have bastardized, including
"give" (which many Poles
spell as "gief").
An example from World
"Trade Polish dude
: PLIS GIEF 1G FOR TABARD!!!!!! PLIS!"
An example from Enemy Territory:
"PuszcadfPL: PLIS KICK CHEATER AIMBOT NOOOOOOOOOB!!!!!!! KURWA"
