Originally used to describe a very heavy cargo being towed by a truck.

"That truck is carrying a big load in that trailer!"

Now usually used to describe a high volume amount of semen released by a man post-ejaculation.

E.g A man pulls out of a woman's vagina and ejaculates 12 big spurts of cum over her body, leaving her glistening in creamy goodness. Her response as she lays back in post-coital ecstasy "Oh Gosh Babe, what a big load!"
After 2 minutes of intense sucking I could not hold back any longer and blew a big load of cum all over her face.
