Social intercourse ?
http://www.thefreedictionary.com/social+intercourse
If you were to use Sexual Intercourse in place of Fucking in a school ceremony most kids would give you a dead stare..
I don't know one kid that was valedictorian that didn't take this very seriously..
Oh and if next year a speech is submitted and it says "between courses it was tough" and the student changes it to "inter courses it was tough" as he is really nervous on stage what then ? Or God forbid if someone forgets to mention "The" or "a" in a speech as they will now have altered the handed in speech to which a precedent has been set.
A bad precedent is being set here for the whole school board. Next year they may not have anyone step up to be valedictorian in fear that a misplaced word will get them no Diploma. These are not kids that cause problems, we are talking "A" students and the most dependable students of the school not the trouble makers.
Bad choice to make an example of because they picked on a model student.
