The "F" relates to the cup size, the "Bombs" refers to what fills the cup size. If you are friends with F Bombs then you are damn lucky. Nothing but good times can be expected when hanging out with F Bombs. If you're aiming for the Trifecta Wow Effect, simply add "Double D" and "EZ-E" to the mix.
EZ-E: "Where's F Bombs?"
Double D: "Dude the last time I saw F Bombs she was getting free shots from the bartender"
EZ-E: "She better have enough for all of us"
Double D: "It's F Bombs, you know she will"
