for the heck of it

No reason needed

For the heck of it means without serious purpose or practical reason—just for fun or curiosity: I applied for the job for the heck of it.

Heck substitutes for hell, making the expression milder.

The phrase often explains impulsive or whimsical actions that don't require justification.
