They normally mean a declaration of love, not love itself, though. Red tulips mean love and fame. Multi-colored tulips are supposed to represent people with beautiful eyes, and therefore beautiful souls. (The eyes are the window to the soul.) yellow tulips symbolize happiness in one's life.
Toe jam is a slang reference to the dead skin cells, sock fluff, surface dirt, sweat, skin oils and bacteria which tend to collect between a person's toes throughout the day. Poor hygienic practices or certain feet-related medical conditions such as athlete's foot can make the appearance and odor of foot jam even more noticeable.
This is interesting to me as the djembe in Africa and in America comes from the kitchens of Africa. Most percussion instruments come from those outdoor African kitchens. Wood and metal make up the kitchen utensils and so it is with the djembe and dunun (the bass drum of the dununba). Even as recently as the 1950s, the djembe was not known beyond African music aficionados and those who grew up with the instrument.
