look up any word, like yeet:
 
1.
Derived from low wattage light bulbs, a Low Watt is an exceptionally tight or miserly individual. Will never buy anything he can’t download, boil the kettle twice the same night or buy a round in the pub.

Never offers petrol money but will always be sure to collect it, goes out having “Forgotten” his wallet, expects family members to fix up his house and garden not just at a discounted rate, but completely free of charge.
Dave: "Tight bastard still hasn't weighed in with the cash for that job we did, Stan."

Stan: "We won't get that. That low watt wouldn't give you the steam off his piss!"
