Caressive
It came up as a suggestion on a spell check I did at work, and I instantly loved the look of it. It is at first glance just an adjective form of the verb caress, but it's more than that. It seems like a combination of corrosive (which is not good) and caress (which is sweet and cuddly) so there is a nice dichotomy going on there.
Also, it reminds me of "Last Caress" by Misfits, which doesn't hurt in the least.
When looking up that word just now, I found this one:
Ninnyhammer
That means a "simpleton" or a "silly person." I'm without a doubt calling my nephews that the next time they are running around giggling and carrying on like a bunch of damn . . . ninnyhammers.
