when your playing a game on online and someone has a really crap connection and lags up the game.
Guy 1: hey join my game on cod
Guy 2: Okay
(game starts lagging)
guy 1: ugh you got tesco connection
a very crappy and laggy internet connection which causes havoc in multiplayer.
me: wtf the guy just lagged across the screen and killed me
friend : he must have a 2 bar tesco connection then.
