1. To pop one. When your little
fella pops up to say hello - an
erection, usually spontaneous, brought on by a sudden event such as a hot, barely-dressed girl walking by.
2. Similar to the above but used in figurative speech to imply an extreme liking for something.
1. We were at the beach last week and Maria took her top off, I was popping one so
bad I had to go sit down in the shade.
2. I was totally popping one when I saw The
Fucking Champs live.
