Combination of "ludicrous" and "lucrative", it denotes something that is totally ridiculous but actually produces a tidy sum in the end.
Two examples of ludicrative actions were people's buying dollar-coins with a credit card and then using the coins to pay off the card to earn card-perks, and the infamous "obsessive coupon-cutter" dude who bought many thousands of foil-sealed cups of chocolate pudding to earn astronomically-voluminous frequent-flyer miles.

The fastest speed imaginable...light speed is too slow! It is extremely dangerous to go to ludicrous speed. It may result in you going to plaid. Also, going from ludicrous speed to a dead stop will result in you being launched across your ship, flying straight into a wall.
Prepare ship...prepare ship...for LUDICROUS SPEED!!!!
