When you've told someone the answers to homework over snapchat and they said thanks, but you don't want to sound too 'posh' by saying "That's ok x" so instead you say this.
p1-"i gtg."
p2-"okkk..."
p1-"omg"
p2-"omg no! i didn't mean like that"
p1-"you're so racist"
*unfriended*
p1-"goodbye."
p2-"wow. i got blocked for saying that."
