“…clog is to block or slow passage through…” from WikiDif
Use the verb to clog, or the past participle clogged, to describe situations where the filament passage is totally or partially blocked. This clog can happen inside the extruder, the hotend, or the nozzle. Knowing exactly where the clog is at, is extremely helpful to achieve a solution.

“…jam is to get something stuck in a confined space…” from WikiDif
Use the verb to jam, or the past participle jammed, to describe situations where an overflow of plastic has filled the internal cavities of the extruder or of other confined spaces inside the Print Head.

Use the word blobs, also know as zips, to describe situations where an overflow of plastic at the end of each layer, or just before a z-hop, is creating surface imperfectionsthat are created by the excessive extrusion of plastic.
A blob is created when the filament is still under pressure inside the nozzle when a layer or segment is finished. This will causea short burst of over extrusion that scars the print surface.
To minor this natural effect usually is necessary to tweak coasting and flow settings.

Use the word backflow, to describe situations where material is overflowing below or above the heat block, although it also flows through the nozzle.
This overflow can be caused by a partial clog, but also by leaks between the nozzle and the heat block, or the heat block and the heat break.
A third reason would be the print speed being too high for the combination of material and nozzle you are using. Different internal nozzle geometries will allow for more or less flow.Pushing the filament to fast with a low flow nozzle will increase the pressure inside it, and material can flow through other paths of less resistance.

“Heat creep is the process of heat spreading irregularly throughout your hot end, disrupting the way filament must melt to extrude.” from Fargo3Dprinting
Use the word heat creep, to describe situations where you have a clog that was caused by heat that spread way up (creep up) through the heat break.
It usually happens after extruder changes (in dual extrusion) to the print head starting a pause, or after you finish a print and you let the printer cool down. The heat creeping up the heat brake makes the material to swell and to stick against the walls of its thinner section causing the clog.

Use the word spaghetti, to describe situations where you have left your printer to do a job, and when you came back the printer or its print bed is covered with a shredded and unraveled cloud of extruded material.
This may be caused by several reasons, the main ones being bad bed adhesion;low layer adhesion; and too much contraction.
Cleaning the print bed before each print or using a good bed adhesion solution can help. Setting the right extrusion temperature, usually higher to solve this issue, that enable a fine material melting and fusion with the layer below can reduce the layer bonding issues. Setting up the proper part cooling, for the material in use, or a closed environment, can help on lowering contraction and the warping forces that peel the part out of the print bed.
