RT's is short for Retard Tingles, or the sensation one gets after watching something painfully embarrassing and stupid. This type of feeling usually follows incredibly dumb commercials, music videos, embarrassing home movies, or Animal Planet.

In gay chat rooms, the term RT means 'real time', as in real time sex. This means that a guy is not simply lookin for a cyber jerk-off session. He wants the full monte.

RT, short for "Russetiden" (The russ period)

The norwegian examination party. The whole party last 17 days, from may 1. to may 17. witch is the norwegian national day.

Russ: The seniors, dress up in red, blue or black and trousers drink themselves shitfaced on "russebusser" trying to execute "russeknuter" for seventeen days straight while still in the middle of the exam period.

Russeknuter (Russ-knots): Spesial tasks the russ can execute in exchange for a "knot" to hang in their examination hat. About one hundred official russeknuter is released for every school each year.

Examples of russeknuter to hang in your hat:
Kongla (The pinecone): Have sex outdoors during RT.
Ølkork (Beer cork): Drink 24 beers within 24 hours.
Champagnekork (A champagne cork): Have safe sex with a representant from the russestyre (The russ parlament)

Every knot needs to have a neutral spotter for them to count.

Russebusser: Busses that groups of russ buy, and spend upwards of $300 000 on to party in during RT. The cost includes paintjobs, speakers, interior and a personal bus driver. Busses from all over the country gater at huge russ parties every weekend in the major cities of Norway during RT.
