I love the way new verbs are created from nouns.
Such as the medschool classic I heard this morning in a clinical skills session (yes, they were finally teaching us to take blood - after 3 years of doing it...). We have a system in place for clinical staff to flag up a potential problem students by filling in a concern form. The form is used for students who have a personal problem, or who seem to be struggling, or are unprofessional (rude to staff or patients, late, low standards of personal hygiene - I kid you not). The form is a bright lemon yellow, hence the ubiquitous phrase:
'That bastard surgeon yellow-formed me for being late to the start of his list!'
Ah, the sweet sweet joy of the evolution of language.
