Bam Margera and Dico speak another language?!?!?!?

i'm pretty sure it's one of the jackass movies. im not sure, forgive me if im wrong. but in one scene, bam and dico are arguing [i can't exactly remember what's going on...] but out of no where, bam and dico break out into another language. i wanna say it sounds like finnish [?], but im not sure.
please correct me if im wrong.... thanks!!!!
