"He loveth transgression that loveth strife: and he that exalteth his gate seeketh destruction. " Proverbs 17:19
To continually be in these "wit battles" to "one up" a person is only walking to destruction. Even in jest one can love strife and in teasing it is still sin to "exalt my gate."
"He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit."
