Input: Text: i'm gunna start by saying me and my dad have a very jokey relationship and were pretty open about everything so it's not weird to see us having an inappropriate joke   anyway,
 
but more context, this is at a family/training bike trail forest complex so there's lots of trails and runs its all very nice (segwaying here too!!!). 

 
was doing a bumpy intermediate down hill cycle trail with my dad. bear in mind the track is extremely bumpy, as in, part of the track is missing and you just gotta go with the flow sort of bumpy.

so yeah, i was just going along with it and my ass was slightly sore from the earlier trails.

as i swing round a sharp bend that conjoins the downhill course and the quiet flat course together, pull in to let some other hard core cyclists go past. thinking that was all, i got back on and riding when i heard another bike. oh it's fine it's my dad i thought


so, i proceed to exclaim very loudly "ahahah dad mah ahnoose, it is hurting" in a very strange foreign accent. 

i turn around. it's not my dad. i pull in and let the elderly couple ride past.
