I went to a linguistics site to translate "tacky even when wet" to Latin. I figured "tacky" would be a relatively contemporary word, so I started with "sticky even when wet." I got this:
lentesco vel ut madidus
I also figured I could reverse-engineer it to fine tune if the Latin-English translation turned out to be wonky.†
So I plugged the Latin back in and here's the English translation:
to become soft or when wet
I don't need to explain why I'm laughing. You feel me, right?‡
†FOOTNOTE (crossed): You know... if the website version of "sticky" turned out to mean "branches" or something.
‡FOOTNOTE (double-crossed): Not *literally*. Trust me, I'm a little oversensitive. If you literally felt me, it'd be the high point of my week. I'd celebrate with champagne and send you a thank you note. Maybe a fruit basket.
