What archeological textbooks and Jurrasic Park taught you about 65 million old reptilian beasts is but a minor bruise on the skin of understatement. The tranosaurus rex is a term donned to those who tricera-top the common man in knowledge, physical capability and vicious sensual lust just to name a few. The ladies jawdrop as the stomp of the tranosaurus sends oscillations up their legs where man could only dream. The 'tran' for short is also a term donned to men popular for fifa knowledge and expertise.
