1. A gigantic black Dravidian Penis, six times the size of the average Aryan Penis. As "Cho" or "Chho" means `six' in various Prakrits (eg. Guzarati, Oriya & Bengali) & "Lingam" is the Dravidian word for `Penis', "Cho-ka-Lingam" means "Having 6 Penises" or "Having a Penis 6 Times Normal Size". As humans don't have 6 penises, it follows that the reference here is to size (ie. volume or weight), & not to number or length.

Now, using the formula for the volume v of a cylinder, one obtains the equation:
v(Chokka-Lingam) = 6*v(Arya-Lingam), ie.
(pi*r_C^2)*l_C = 6*{pi*r_A^2*l_A},
where r_C, l_C & r_A, l_A denote the radius & length of the Chokka-Lingam & the Arya-Lingam respectively.

So a Dravidian Penis that is 73% thicker than the width of an Aryan organ, & twice its length would qualify as a
"Chokka-Lingam". Since the Prakrit & Sanskrit sexologists found the Aryan Penis to average 6 inches (8
angulis or fingerwidths), this corresponds to a length of 12 inches. This is one third larger than the Shudra
Penis, said to average 9 in. (Ananga-Ranga 3.1) & such specimens are well-recorded.

2. A Dravidian name, nick-name & surname, assigned to well-endowed men. In general, Dravidian names are brutally honest about the bearer's penis. Given the requirement of the Aryan Penis to contract & avoid frost-bite in the cold Northern winters, the massive Chokka-Lingam - both name & member - is almost exclusively found South of Marathwada.
