A lengthy penis (not necessarily 12 inches, but not under 10), a hot dog, or a sub (See: hoagie). All are good on buns.

Dave: Hey- is that a footlong?

Burt: Sure is.

The size of my ex-boyfriends dick

When he slid into me....heaven on earth
When I gave him the blowjob of his life
As he cummed in my mouth
Oooh, the salty taste
Mmm I need me some more of that.
