Noun. The last toke you take before you stop smoking weed because you are as high as you want to be.
"No thanks man, that last one was my topper."

"No dude, I topped out already."

"I had to pick up the phone just as I was exhaling my topper! I hate talking to people when I'm high; it was like, "I know I'm talking too much, but I don't know what I can leave out of what I'm saying!"
