A masturbation technique where you take a jar of Smuckers (your choice of flavor), open it and insert your penis, then proceed to masturbate with the jam.
OPTIONAL: After ejaculating into the jar, make a sandwich or bagel with it and give it to your girlfriend, hated brother, or enjoy it yourself.
Random Guy: I totally made my gf a Smucker Fucker sandwich last night!
I finally had a threesome with a midget, I can now mark that off my slucket list;
also
Last night I am pretty sure I wiped the last 3 items off of my slucket list, I can now die happy as long as I don't have HIV.
