Almost always used with the word Roflwaffles, basically its this random word you can add in when something funny happens just to add to the moment or kill the moment. A word developed while playing fps games..
Can be used at any time.
even screaming it out in public (mainly a car) ROFLWAFFLES WITH LOLERSAUCE
A delicate sauce spread proportionately over the victim of someone's mistake, defeat, or even your own victory. Taste's great with a large ! at the end.
1) "GG, uninstall, spread some lawlisauce over your cpu."
2) "Man, my account just got hacked...I have nothing" "LAWLISAUCE!"
