Fun Fact: In the NFL, it's perfectly LEGAL to tackle an opposing player by the hair if it's hanging out of the helmet.
Funner Fact: Players who pull hair deserve to get their ASSES KICKED because they've made things "personal" ... so says LaVar Arrington.
The former NFL defensive stud -- who has some luscious dreadlocks of his own -- says there's an unspoken code among players regarding the "mane" ... and violators NEED to be dealt with.
Of course, Arrington must REALLY hate guys like Jason Babin (JAX) ... who ripped Andre Ellington's (ARIZ) dreadlocks out of his skull during a game earlier this season ... and then displayed it to the crowd like a trophy.
No, LaVar doesn't like that one bit ...
