When somebody that you don't like and/or has bad skin comes up to and rubs their face against your body. Its unwanted physical contant, not out of affection.
1) "I was in english today and he just came up and keeksey rubbed my face!!"
"Shit! Man.. You ok?!"
2) "I was just standing there and she came up and rubbed her face against me...! I feel dirty.. I need to wash."
"SHIT YOU'VE BEEN KEEKSEY RUBBED!!"
