Waiting for the first Yammer lawsuit due to corporate data being leaked...
I thought this might be an oversight, so I did a quick Google search using variations of "Yammer", "India", "penis", and apart from your comment could not find anything in the first 5 pages of results for any permutation.
The only thing that was even mildly related to India is "Yama" but he's a hindu deity of death, nothing to do with genitalia.
Yammer is an english slang word for "to speak incessantly about nothing" which pretty much sums up twitter.
They sell pretty well around here.
