I e-mailed some photographs to someone cooler than me (not a very small group), and in his reply he says, "The ones from spanish 3 are cool to . . . But the one of us playin' cards is evidence. Thanks you just made my week." (emphasis added)
Ignore his choice of homophone. What does he mean by "evidence"? None of Urban Dictionary's definitions seem to fit, to say the least. Is it a new way to say "cool"? Or am I overanalyzing, and does he literally mean that the photograph is "evidence" that we were playing cards in Spanish 3?
Thanks for your help.
