Spitting in soccer (and pretty much any sport) is universally decried as the greatest unsportsmanlike act. When German Rudi Voeller and Dutchman Frank Rijkaard started exchanging heated words in this round of 16 clash at Italia 90, it all went too far. Rijkaard spat at Voeller, who complained to the ref to no avail. The trash-talking carried on for a few minutes until they were both sent off, so Rijkaard had another go, leaving the contents of his mouth hanging from Voeller's mullet.
