In sports: Feel Gold instead of Field Goal. Also, is it Brent Favre's choice that his name be pronounced Farve?

In medicine: the use of Visualize for See. I can visualize my gall bladder in my imagination, but I can see it on an ultrasound image.

In standard English: the coining of new, constructed terms when there is a perfectly viable extant term. Now, I truly enjoy the constructionism English allows, what with nouning verbs (or verbing nouns), adding -esque to anything, and so on. But why Wellness when we have Health?

In slang English: I don't mind Going for Saying nearly as much as I'm comma like comma. As in, "I said 'A' then he went 'B' so I'm, like, 'C'..." - and so on.
