Seuce has multiple definitions and can be used in a variety of ways. As a verb, seuce can be used to replace any other word in the English (and some Spanish) language. Most typically seuce is used to replace the nouns "suck" and "pick up".
The word seuce derived from the game of euchre. The French word "coupe" replaced the word "cut", and in time the term "suck out trump" was also made French by changing suck to seuce.
Example: "Yo Man, can you seuce me from my house around 8:15pm?" or "He is probably getting seuced from Rebecca" or "Man, you just seuced my last spade!"
To smoke a cigarette while dropping a deuce (#2, lay cable, etc. etc.). From my knowledge, smoking while dropping a deuce feels great and aids in the release of poop which is most likely a mental thing. Give it a try sometime if you're already addicted to cigarettes. Kids: Cigarettes are BAD.
