Sex position including one male and one female partner. The male holds the female upside-down and sideways between his legs (creating almost a scissor-like leg position) and proceeds to jump up and down while simultaneously jamming his raging boner into either her anal or vaginal crease. The result is a massive jizzbomb, hence the name.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed
