smelling your piss

This is an old school term that I am very surprised that isn't on here. When one thinks they have come of age or at a stage in they life that that they can talk and act a different way towards others...mainly seen in a negative connotation. The term is a reference to one's bodily changes as one gets older: what one eats and drinks as they get older can change the actual smell of one's urine as it becomes stronger...

Smelling your piss: alll of a sudden he thinks cuz he got that job up at UPS and he makin' a lil money, he can get funky wit his momma and them talkin back to them like they aint shit...over there smellin' his piss
