Be careful how you wipe your nose.
It sounds like something a mother or father would teach their young children about regarding hygiene or keeping their clothes properly clean.
But no, we are actually talking NFL rules on this one.
Cowboys wide receiver CeeDee Lamb has used the “nose wipe” as his celebration since leaving Oklahoma and becoming a Dallas Cowboys receiver in 2020. Now we learn the NFL has said enough is enough. They have learned that Lamb's "celebration" is actually conveying some sort of gang-related message that someone is not trustworthy.
But of course that means not trustworthy according to the standards and values of some modern-day gangs.
