look up any word, like jamflex:
An instance in which an individual is between two hyper-intelligent members of the gender he/she is interested in banging. The sandwich of knowledge is a major turn on for the individual, who generally finds super smart hotties irresistable. The sandwich may or may not become sexual.
Dude, last night, I was in the middle of the BEST sexy sandwich of knowledge.
