Nah, but I grew up in the countryside and part of that territory comes with picking up insects and studying them. And ladybugs would secrete this fluid that would smell and stick to you fingers and when you're a little kid, running around in the garden, playing with bugs one minute and picking strawberries the next, you end up putting those fingers in your mouth at some point and tasting the bitterness of ladybug "leave me alone"-juice.
