If teens and adults use, hmm, maybe close one eye lah but small
kid, just go to them and say "what did you say kid??!!, you wannaa
me to slap you upside down??!!" Girls only words come out but it's
usually guys who words and actions. The word wtf is stfu is
becoming common. Definately girls who likes to keep scolding bad
words ought to be dumped by their BF.
