the.com/wild oats

The crop you sow when you're too young to farm responsibly.

means The reckless, pleasure-chasing escapades of youth, especially before settling into a responsible adult life — as in 'sow one's wild oats.'

from Wild oats are a real weedy grass that looks like cultivated oats but produces no useful grain — so sowing them was a farmer's symbol of wasted, foolish effort. The phrase appears in English by the 1500s as a metaphor for a young man squandering his energy on worthless pursuits rather than productive ones, and it stuck specifically to youthful misbehavior and casual romance, carrying the implied promise that he'd eventually grow up and sow something worth harvesting.
