Termination is the practice of making phone calls to people anonymously and then proceeding to only use sounds, music and quotes from the first three 'Terminator' movies during said phone calls.
The most frequent type of termination is done with the main Terminator theme opening the call then followed by classic Terminator quotes such as "RELAX", "I need your clothes, your boots and your motorcycle", "Uzi 9 millimetre" and "I'll be back" with the theme playing in the background.
Prime candidates for said phone calls are those that share their names with the main cast of the Terminator films
"I haven't spoke to him in a while, I think he deserves a termination"
"I got woke up last night by my phone, at first I thought it was my mother but it turned out I'd be terminated"
"If I find that terminator, i'll turn his bowels into a garden ornament"
