"Some people are good with words, others um... thingy"
Yesterday, I've learnt that I am an "Ectomorph"
From Dictionary.com
An individual having a lean, slightly muscular body build in which tissues derived from the embryonic ectoderm predominate
Thanks Dictionary.com, for clearing that up *shrug*
A credit to Maximus for teaching me the word (visit again next week, when we'll look up "pachyderm").
