If you want to play another undertale fangame, then TS!Underswap is a good one. As of now, the game has only been completed up to Snowdin, but it still has decent length(so far the Ruins+Snowdin are significantly longer than they were in Undertale). Imo the writing also feels a bit better than other UT fangames like Yellow and Deltatraveler.
I hadn't heard it before! I'm used to the phrase "shits and giggles," which the phrase in the game is clearly a non-sweary version of, like saying "aw, fudge" instead of "aw, f***"
