Nope nothing of the sort.
The name actually comes from a conversation with a friend in high school. I've always been into hard core metal, punk, thrash, alternative music, well I had a friend in HS in my drafting class who was also a fan of the music and one day we were just spit balling names for hypothetical bands....I came up with "The Thrashing Pink Cows" and when I started coming on line and needed a user name I remembered that conversation and band name, so I just dropped the pink, and became Thrashingcows. ;)
