Why do some Catholics kiss their thumb after making the sign of the cross?

Full Question

I notice that Latinos in my parish kiss their thumb after making the sign of the cross. Why?

Answer

They actually are kissing a cross formed by placing the thumb and forefinger at right angles. Kissing the cross (as we do on Good Friday) is an ancient gesture of devotion. It implies a humble acceptance of one’s own cross in imitation of Jesus.
