I need the spelling a trifle would make as you spoon a dollop out of the bowl. Sorry if trifle is unfamiliar to American readers but it's a dessert comprising sponge base, then jelly/jello, then custard and finally cream. As you spoon it out it has a tendency to form a suction action, creating a very distinct noise, but how to spell it?? I went with Sccchlop! but I'm not sure it conveys it accurately.
(I wouldn't get too hung up on this one - there's clearly no definitive right, but) I liked your rendition Jud Although... was that for the dollop peeling off the spoon, or the dollop hitting the recipient bowl (I assume the latter)? For this reason, you may want a two-parter, like I.A. By the Barn has suggested. (And now I want trifle... the most elaborate thing I ever cooked was a trifle - had to figure out how to veganise every component Worth it!)
In actual fact @Sifunkle the 'suction' sound in question happens when the dollop is being separated/lifted from the rest of the trifle. It's the same as the sound you get when pulling a boot out of deep mud. Like you say, though, daft to get caught up in this. And I'm not - just thought it might be a fun question.
Ah sorry, I misread your first post! Still think it's fine, but I'd maybe go schlrp over schlop (+/- letter repeats) if the dollop gradually comes away rather than springing free... hah
