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.
Toe jam is common non-medical term used to describe the 'gunk' that accumulates between the toes. It is a combination of dead skin cells, sock debris, dirt, body oil residue, fungus and bacteria. Scabies, a parasitic skin mite, often burrows between the toes and is associated with poor hygiene. Not all toe jam is the same, however.
