Tandem-biking

The logistically difficult manoeuvre of walking as a couple whilst engaged in anal sex without withdrawing.

We were hard at it when we noticed the sunset; so we started tandem-biking over to the balcony.

Tandem Stupidity

An act of stupidity thought of by one person and executed by another.

This type of stupidity is associated with initiations of various types (usually dumb)and military service(hopefully not as dumb)

Was that real what I just seen or an act of tandem stupidity ??

Is that person really crazy or is there someone screaming through them in an act of tandem stupidity to discredit them?

Missouri Tandem

The Missouri Tandem usually works best for threesomes of 2 men and one woman. One uses the vagina, whilst the other uses the anus. When the female is on the edge of orgasming, both the men suddenly pull out and flip her over, so the man who was penetrating her vagina is now penetrating her anus, and vice versa.

Bandit and I were giving Emily a good romp. When she got close, we gave her a Missouri Tandem! Good times.

Tandem grave

Used to swear on something serious, showing you’re not lying, not playing, and speaking with full truth or intensity. Similar to saying “on God,” “on my life,” or “on bro nem.”

“Shorty badder in real life than IG, on tandem grave.”
