Giving cash to homeless people at the roadside. Best to give bills/coins while traffic is stopped, but more challenging if done on the move. Looks pretty smooth and cool to other drivers if done correctly; usually at slow speed and not holding up traffic. The recipient is demonstrably thankful.
After the light changed, the motorist in front if me was drive-by donating. Handed off a few bills to a homeless person on the median while going about 15 MPH.
A small piece of information. Derived from the word ken, used often in the scottish language and is synonymous with knowledge.
Person 1: "Hey I don't get this shit. How do you solve this problem?"
Person 2: "I got that one. Give me some kenlets on this assignment and I'll help you w/ that one."
