#SocialMedia is largely about reading stuff you barely understand about people and things you know little about, and having to look up #words and #phrases to see that they mean.
“Sowing wild oats” isn’t about sex (though it can be used like that) but rather about the folly of youth. Wild oats don’t need sowing (they’re wild!) but are hard to distinguish from cereal oats. “Sowing your wild oats” means you’re using your time in a foolish way associated with being young and inexperienced/reckless/inattentive.
Example:
“In my youth I thought I’d make a living as a DJ. Dad tried to dissuade me but mum said I had to sow my wild oats.”
