(Note: Ridiculing isn't necessarily teasing. Teasing implies saying or doing something unkind or ridiculing towards another, but that was done just out of silliness, which is why it's common to say, "I was only teasing. I was just joking")
"You could make George Bush look young," I ridiculed my wife before she threw my pillow and blanket on the couch.
After Henry ridiculed me today at school, all the students bursted in laughter.
ridicule may or may not be done in a teasing manner. Some ridicule hurts
John is usually just teasing when he ridicules me so I never make anything of it.
