A rusty canister takes place when two gamers who are attracted to one another meet for the first time. This act is performed by both parties standing on top of a bed while rotating until the dizzying effect causes them to fall onto the bed.
Burt and Janet decided to meet in person after months of playing Fallout 76. They immediately jumped in the bed and did the rusty canister before falling into each others arms.
