If someone flames me, i reply with positive behavior
It usually makes them stay silent or they get a good chuckle out of it due to how ridiculous are my replies
Examples
Person:Fuck You Me:I Love you too bae~ <3
P:OMG NOOB SUCH MISPLAYS M:Such fabulousness right?!
P:I am gonna hunt you down and kill you M:Want the booty? Come and get it champ >:3
Getting Killed:Oh Dear~
Losing:Good game
Yes, this actually made me chuckle several times after seeing my opponent reactions to it,and usually makes everyone stop being toxic due to how akward i sound (Or outright mute me)
