This term comes in many forms. It can be a racial term of someone of Indian descent, it can be a term for a small dog or child, or it can be a term to call someone below average height.
Someone that feels the need to overcompensate in any way,for any kinda shortcoming; ala small,loud barking dogs that bite your ankles to show you their workin' wit' sumthin'..
To the meathead at the bar that's all angry & likes to kiss his muscles, "Dude! Stop bein' such an ankle-biter!"
