A young male who doesnt swear and happens to be really cool. In addition he is also comparatively quite mature. A yousuf also MAY have extremely large genitals.
However, to be a true yousuf you have to wear spectacles!
Teacher: If you dont sober up and become a yousuf I will send you to the principal

To friend: OMG you just said WTF and to think I thought you were a yousuf.

Stop trying to be a yousuf on front of that chick, its just not you.
